Account age calculation?

Sadly I have no clue how it works and it seems wrong since you should be on year 10 now, am curious if someone else knows the reason for it!
That said, you wrote 2013 twice, not that it matters since I assume everyone understand but still ^^

Perhaps it only checks the month and it will change on October 1.

It subtracts the days you were banned from the total of the age....

Just kidding....I have no clue why and no glue to fix it.

I suspect the unsatisfactory solution is the probable satisfactory solution!

it's also similar with the giveaway end times, e.g a giveaway that ends in 12 days from now is marked as "1 week remaining"

so it could be what Mitsukuni suggested and it only looks for the next week/month

You can see from view-source:https://www.steamgifts.com/user/SilentGuy line 273 that the calculation is made on the server side, 9 years is present already. The tooltip is then calculated in the browser from the supplied timestamp (1379190374), but that works correctly (you can drop it into https://www.unixtimestamp.com/ or just put new Date(1379190374000) into the JS console of your browser - it needs milliseconds, hence the 000 added).
A thing I can imagine that this field is stored in the database. And then it may be updated only when "something" happens to your profile, like synchronizing with Steam could be that something, you can try that. Another possibility is that it uses a homebrew calculation instead of a library call, and something is oversimplified in that calculation. For example in an extreme case treating all years 366 days long the turnaround will be 8 days late, on next Friday.

I would think it would be calculated on the server, but is the date correct on your computer? I remember something about having an incorrect time zone selected in Windows affecting giveaway times. It's probably not the problem, but you checked so many other things already, so why not :)

Well, from my experience once you hit 10 years it stops counting. Or, maybe it starts counting in decades.
When you hit that magic 10, is the counter gonna gonna be more or less annoying? :)

Took 4 or 5 days for me, i got super confused and made me think it might was the 9th cakeday instead the 10th (and i forgot how to count)

This is odd indeed. I see it still shows "9 years ago", and it is nearly 2 days late...

(And, as you said, "1 decade ago" does exist -- my profile is one of them).

I am eagerly waiting now for your turn -- maybe in 30 minutes or so, when it turns 10 years 2 days?

Cheers!

Edit: but you did get your cakeday 2 days ago?

Edit 2: I see "1 decade" now. YAAAAAAY! :D

seems you finally got your magic registered a decade ago status.

Let's push for Level 10 now, you can do it :)

Hey. can anyone tell, how can I know my account creation date as I regularly clear my inbox.
