why my daily puzzle streak got resetted?

I had about 60 days streak. yesterday i did 5 daily puzzles (mon-fri) and i realized that now i have 3 day combo and i have no idea why.

You have to do the daily puzzle each day to keep you streak. You can't do them afterwards. And it is not your own calendar days but chess.coms.

its not true that i have to do the puzzle every day. i was doing previous puzzles from same week several times and i had my streak untouched. so... you're wrong

not sure if i wrote it correctly so im gonna repeat it. i did my daily puzzles *NOT EVERY DAY* and i still had my streak. yesterday i were doing the same thing as i did MANY TIMES BEFORE: i were doing puzzles from 4.09-8.09. and now my streak is equal to 3. it means that i must have started "doing it every day" in 6.09. so idk how you got that information but you are 100% wrong

live with that fact

and now im begging someone that knows a little bit more about chess.com to answer my question

As said: it is not your own calendar days, but chess.coms. In Denmark it goes from 9am. So if I do a puzzle at 8.50 and another at 9.10 I have made 2 days. But if I make one 8.50 and the next day make one at 9.10 I will only have 1 day.

The site added a short window to do a daily puzzle after the next day, but if you're outside that window, you'll lose your streak.

ok, i understand. but why then after i did 5 puzzles in friday i have 3 days streak? it would mean that i did them in wednesday but i didnt.

Depending on when in the day the puzzles were completed, it's very possibly three of the puzzles fell within the

ok i understand. thanks for help.
