Loving the hats!

So much so, that I'm trying to get one :).

I have already achieved the criteria for several of them, but before I enabled the hats functionality.

So my question is: Does the progress towards them start on enabling them, or will it back-date from before then?

    Looks like it is retrospective, but that it takes time to get them (probably a batch job running every x minutes).

Unless I've misinterpreted this post, L'chaim is the only hat that's awarded retroactively. All other hats are based on your activity from the 19 December 2012 00:00 UTC (and not the time when you opted in).


Shawn Chin is correct -- L'Chaim is the only hat being awarded for activity that started before the event began.

All hats must be earned with activity that occurred after 19 December 2012 00:00 UTC.

  • So all activity from 19 December 2012 00:00 UTC to when I actually enable those awesome hats still count?

    @ShawnChin Yes! Even if you decide you love hats later, your activity counter started at midnight UTC on 19 December. :)

    Thanks for the clarification. I've updated my answer to make this more explicit.

I earned the L'chaim hat (on main site) as soon as I enabled hats today so it definitely back-dates this one seeing as that badge was for posts or votes on the 16th :)

I have a feeling that some may not be back-dated however such as making 5 edits. You will likely have to earn these through meeting the defined criteria after you have opted in to the winter bash.
