Weird day counter update

Hey quick question. I am currently on my streak achievment, more precicly day 115 for me. Something weird just happend though. About an hour before midnight my counter suddenly went up after upvoting a post. I thought that was weid because I most certanly already upvoted somthing today (btw I always upvote right after midnight to make sure I don't loose my streak, so that was very weird). And now after midnight the counter won't change.

Don't get me wrong I looked at my calender and it's the right day, but apperently it just counted/started earlier this time. Has this ever happend to anyone where Reddit (The App btw) started to count too early?

I just want to make sure nothing is broken.
