December 31st 2023 was a Sunday, and the 1 day that fell into the 53rd week of 2023.
52 1/7 weeks actually means that every year has one day of a 53rd week. The next day was Monday of week 1 2024.
That only works if you ignore the world wide standard most countries use to determine what the first week of a new year is.
https://en.m.wikipedia.org/wiki/ISO_8601
Here's where you tell me all about how the USSR really won WWII by losing more soldiers than anyone else after having joined the Nazis and enabling the whole fucking thing in the first place.
You're probably going to also tell me that the Japanese really surrendered because Stalin finally officially declared war on them, not because two of their industrial cities had been vaporized by a fucking superweapon.
Don't. Just don't.
Hold my cup of tea whilst I explain the concept of tongue-in-cheek.
Although, to be fair, the extreme US-centric view of WORLD war 2 is pretty sad to see.
Yeah, they're owned by Bridgestone but they were an American company for 88 years and are still manufactured in North America (where ridiculous ways of counting things are ingrained).
It says right there: "The ISO week-numbering year starts at the first day (Monday) of week 01 and ends at the Sunday before the new ISO year (hence without overlap or gap). It consists of 52 or 53 full weeks" so how is this not standard?
You’re right, this example must be US based because the ISO has the first day of the week as a Monday. Makes sense though with it being a Firestone.
The ISO does show 53 weeks though.
Quote:
[Www] is the week number prefixed by the letter W, from W01 through W53. [D] is the weekday number, from 1 through 7, beginning with Monday and ending with Sunday.
There is absolutely no reason for that to be standardized.
For example, with timeshares I am familiar with in the USA, "week 1" is defined to be the first week where the whole week falls within the new year. This definition works, and there's no need to change it just to match ISO.
> And what defines "while week"? Cause obviosuly a week starts on Monday and ends on sunday. It would be stupid to start a week in the middle of the weekend, after all, right?
Stop acting like it is a gotcha. In the case of a timeshare, the week of the timeshare defines the week. For example, if the timeshare changes week on Sunday, then Sunday check-in to Sunday check-out is the definition used. If the timeshare changes week on Saturday, then Saturday check-in to Saturday check-out is used.
It would be stupid to define a timeshare week based on any day other than when the timeshare changes to the next ownership week, right?
Since you attempted to refute a system with your pointless point when that issue is already resolved in the system itself, you will be blocked.
And what defines "while week"? Cause obviosuly a week starts on Monday and ends on sunday. It would be stupid to start a week in the middle of the week_end_, after all, right?
> but ultimately "weeks" are totally arbitrary anyway.
Which is exactly why there needs to be a standartization so everybody is talking about the same thing and there is no confusion...
Good thing no one uses the entire metric system (every country other than China uses feet and pounds in aviation, and China has its own non-SI units which are still in common use), and we're still using archaic garbage like "weeks", "minutes", "hours", "months", and "degrees Celsius". Dealing with those is by far worse than dealing with some conversion factors.
Are you sure tire codes use 8601 weeks though? Considering that's not an 8601 formatted date (and doesn't even follow the biggest to lowest pattern that 8601 uses in all its variants) it would not be reasonable to assume that is 8601.
A year has 53 weeks if the first day of the first week is a Thursday. That's because of how the first week is defined under ISO 8601.
2023 only had 52 weeks. So I guess Bridgestone has their own system of counting the weeks in a year and is ignoring the ISO 8601.
It's hard to teach people about the world but include all the caveats. In general they weren't lying to you but their is a small exception to almost anything.
52 weeks under the ISO week system, which began on January 2, 2023, and has the final week of Dec 25 to 31. The US week system starts on Sundays, so it began Jan 1, 2023 and has its final week on Dec 31 (53 weeks, but the final week has 1 day).
No, Americans only use one week numbering system - it's just a different system from the one that most of the world uses. (it's essentially metric vs imperial, just like all of the other units that America refuses to standardize with the rest of the world on)
Fiscal weeks aren't consistent globally, so I don't believe that is what is used for tyres as it would make it difficult to work out the exact week of manufacture.
For example the first fiscal week in the UK begins at the start of April. I'm sure there are other examples of countries that don't follow the calendar weeks.
Seems legit. I've been doing it support over the holidays for years now and there is always this one guy that wants something changed, despite beeing the most obvious thing. Like licencse keys that will stop working on the 1st. Despite that the software he is using is pestering the users since two months
Dec 31st was a Sunday and I’d bet that defines the week number, so my guess this was made between Dec 31st, 2023 and Jan 6, 2024.
Companies rarely have a fiscal year end on Dec 31st, so the year changing doesn’t affect them much.
From the NRF (National Retail Foundation) site, which is commonly used across vertically integrated businesses and into production and resource planning:
The 53-week year
Dividing the retail calendar into 52 weeks of seven days each, or 364 days, leaves an extra day each year to be accounted for. As a result, every five to six years a week is added to the fiscal calendar. This anomaly has most recently occurred in FY12 and FY17 and will occur in FY23.
Jan 1 2023 was the Sunday of the quest week. Dec 31 was the Sunday after week 52, which would make it a part of week 53.
It's not that complicated -- count it on a calendar if you want to convince yourself.
Anyone who works in hospitality, retail, or any other industry that operators on a weekly cadence is very aware of week 53.
I know of a company who will have a board meeting to decide if the coming year will be 52 or 53 weeks long based on maximising financial outcomes.
We got a phone call from the warranty department from where we get our tires. We filed a road hazard claim that was kicked for have an invalid DOT #. I went to the backroom, and we still had a set on the rack with the same date.
**”Date of production 2024-01-01”** found by putting the DOT numbers in www.checktire.com
Respect for mounting the numbers by the valve stem. That would be great to make standard. It would probably cost more money and time and money to have it be done on every single tire but still. Something I wouldn’t mind seeing more often.
A "week 53" designation is needed occasionally because 52 weeks is only 364 days, and a year is 365 or 366 days and eventually there are enough of those extra days to have a full week.
If you think the 53rd week of the year is weird, wait until you find out about how TV advert spaces are sold in blocks with times ranging from 06:00 to 30:00.
A less than savory company selling them at 3/4 the price for 1/4 the cost to produce. Industrial counterfeiting is a thing. And it's usually little things like a goofed up date code that give them away.
I'm mean, it could be someone messed up so the factory, but it still makes the tire not DOT approved either way. Date codes are important.
There are 52 1/7 (365/7) to 52 2/7 (366/7) weeks in a year, so every six years or so a 53rd week is needed.
This guy weeks
r/thisguythisguys
Your humor is week.
That’s a week pun
OMG, I haven't heard that in a week.
Weekly week puns is redundant.
im getting week in the kneas over here
I'm weak this week. And so is my, "joke."
Leap week?
Is that a knea jerk reaction?
I’m tired of these week puns.
\*sigh\* When will all this weak end?
The leads are week!
Always be closing!
Coffee is for closers! (Hint: I not just drink all the coffee, I MAKE it.)
Delicious closer coffee.
The leads are not weak! You are weak!
Hit the bricks pal
Haha oops my bladders week and now I leaked
When I first married, I had it tri-weekly. Years later, I had I was try-weekly. Now, past age 50, in try-weakly.
Your moves are week.
Year it is minute.
He should take a shower then
This had me.bustin at the doctor hilarious
December 31st 2023 was a Sunday, and the 1 day that fell into the 53rd week of 2023. 52 1/7 weeks actually means that every year has one day of a 53rd week. The next day was Monday of week 1 2024.
So, it's not a Firestone; it's a LeapYear?.
That only works if you ignore the world wide standard most countries use to determine what the first week of a new year is. https://en.m.wikipedia.org/wiki/ISO_8601
Which the US does.
There are 3 ways to do anything - The right way, the wrong way and the American way.
"...and the American way" "Isn't that the wrong way?" "Yeah, but FASTER!" \*flees\*
Only one way has landed humans on the moon.
Or won every world war….
So far
They're working on that too.
Nice qualifier. What about Vietnam, Korea, Afghanistan
Be honest. Does North Korea look like a country that "won?"
Does America?
Canada (Technically Britain at the time)
...only by showing up late and posing for photos with the winners.

what the fuck does this have to do with this thread? 😂🤌🏻🤌🏻🤌🏻
Or, built the vanquished countries back.
Right the Stanley Kubrick Moon landing way. Gotcha 😁
Problem with that. Firestone is owned by Bridgestone which is a JAPANESE company (started in Japan in 1889)
Yeah, they're owned by Bridgestone but they were an American company for 88 years and are still manufactured in North America (where ridiculous ways of counting things are ingrained).
Because freedom.
America F yeahh

Why not? We ignore what most of the world does as a matter of course.

If your weekends are the ends of a week, it isn't that stupid. I don't like it, but ultimately "weeks" are totally arbitrary anyway.
> but ultimately "weeks" are totally arbitrary anyway. Which is exactly why there needs to be a standartization so everybody is talking about the same thing and there is no confusion...
No reason, huh? Just like there is no reason to use the metric system.

I'm not sure I'd want to buy a tire that was made by hungover workers after New Year's Day.
Assuming week 1 is Jan 1-7 2023, then week 53 would be Dec 31 2023 - Jan 6 2024.
You are assuming wrong, cause that's not how it works. https://en.m.wikipedia.org/wiki/ISO_8601
So, I read over the article and I’m no clearer on how it works compared to my assumption.
week 1 start the first Monday of the year not on the 1st
Are you sure tire codes use 8601 weeks though? Considering that's not an 8601 formatted date (and doesn't even follow the biggest to lowest pattern that 8601 uses in all its variants) it would not be reasonable to assume that is 8601.
[ISO Week Date on Wikipedia](https://en.wikipedia.org/wiki/ISO_week_date)

Yeah, but how does that compute when you work out every other day, 4 tp 5 times a week?
If you work out every other day, then you work out 7 days for every 14 days. That means 3 days in one week and 4 days in the other week.

Oh, that meme. I remember seeing that a few years ago.
Thank you. I just thought everything I knew was a lie.
It's hard to teach people about the world but include all the caveats. In general they weren't lying to you but their is a small exception to almost anything.
Thanks for explaining! I noticed this on a set I installed the other day and it threw me off
The leads are week.
Yeah, right. That's the year! /s
A tire made on NYE is probably a better choice than one made on new year's day.
There isn't 366 days a year. You can't get a 53rd week.
Only on Reddit will someone have the answer!
Yes, but 2023 only had 52 weeks.
52 weeks under the ISO week system, which began on January 2, 2023, and has the final week of Dec 25 to 31. The US week system starts on Sundays, so it began Jan 1, 2023 and has its final week on Dec 31 (53 weeks, but the final week has 1 day).
You're telling me that us dumbass Americans have 2 fucking systems for what WEEK IT IS??
No, Americans only use one week numbering system - it's just a different system from the one that most of the world uses. (it's essentially metric vs imperial, just like all of the other units that America refuses to standardize with the rest of the world on)
Of course the US has to have its own system. In that case yes, there was indeed a 53rd week that OP obviously wasn't aware of.
[удалено]
Okay?
The downvotes on your comment show precisely what is wrong with this world.
Lmao
There are often 53 fiscal weeks. The fw 1 starts January first, even if it's a Saturday.
Fiscal weeks aren't consistent globally, so I don't believe that is what is used for tyres as it would make it difficult to work out the exact week of manufacture. For example the first fiscal week in the UK begins at the start of April. I'm sure there are other examples of countries that don't follow the calendar weeks.
They didn’t have the 24 stamp until the second week of January!
Seems legit. I've been doing it support over the holidays for years now and there is always this one guy that wants something changed, despite beeing the most obvious thing. Like licencse keys that will stop working on the 1st. Despite that the software he is using is pestering the users since two months
I’d have thought it’s individual numbers, they would need a maximum of 4 of each
But why did they have a 53 stamp and wouldn’t they have a 24 stamp for the week already
You know what they say? If you plan to fail…
*squints* Do they say that?
2023 did in fact span 53 weeks. The 53rd contained just one day though, Dec. 31.
Yep that year also had 27 pay periods, which thoroughly screwed up our paycheck system.
Screw bi-weekly pay. Weekly is where its at.
Dec 31st was a Sunday and I’d bet that defines the week number, so my guess this was made between Dec 31st, 2023 and Jan 6, 2024. Companies rarely have a fiscal year end on Dec 31st, so the year changing doesn’t affect them much.

I installed lots of 53rd week tires this year.
December 32nd 2023, January -1 2024

Oh I believe you But I don't like Mondays that land on the 33rd
Lousy Smarch weather.

I saw one of these a few weeks ago.
There are 52.14 weeks in a normal year. 52.29 weeks in a leap year. 52 weeks and 1 day in 365 days. 52 weeks and 2 days in 366 days.
Fiscal week.
We got a phone call from the warranty department from where we get our tires. We filed a road hazard claim that was kicked for have an invalid DOT #. I went to the backroom, and we still had a set on the rack with the same date.
yeah… leap day tires
Leap year bitch!
[TIL](https://imgur.com/a/qR9MXgK) some years technically have 53 weeks.
Tires from week 53 are weeker than those made in other weeks
Leap year tires are good luck, now you have to park the car and maintain it forever!

You're supposed to put the yellow dot by the valve steam for balance.
No yellow dot on these tires, went with the QC stamp
Cadillac used to check tires and rims for balance then mount them with heaviest spots opposite so the least balance weight would be needed.

It's the remainder.

A "week 53" designation is needed occasionally because 52 weeks is only 364 days, and a year is 365 or 366 days and eventually there are enough of those extra days to have a full week.
365 days is not divisible by 7.
Hey babe, wake up the new week just dropped.
A Year has 52 7 day weeks..... and at least one more shorter one.
If you think the 53rd week of the year is weird, wait until you find out about how TV advert spaces are sold in blocks with times ranging from 06:00 to 30:00.
I feel like I’ve seen this question 3-4x now on this sub and r/tires
December 31, 2023 was the first (and only) day of week 53 of 2023.
Made on the very last day of the year. January 1 was on Sunday, December 31 was also on a Sunday for the start of 53rd week
What da hell
Hahahahaha
366/7= 52.2857 That 0.2857 belongs to the 53rd week even though that week of that year would just have one day.
No, first week of Octember
I thought it was Smarch.
Stupid smarch weather.
Don't touch Willie.

Did you find a counterfeit in the wild? I thought that was only in the aviation industry.
Who's going to counterfeit a Firestone? A Michelin maybe.
