Hi everyone, This year, I have solved at least one problem every day. However, on July 13th, something strange happened.
I solved a new problem and then closed the website. The next day, when I checked my streak status, I saw that my latest submission hadn’t been counted, so my streak was broken.
Am I missing some information about how Codeforces streaks work?
Please help me T_T. I have tried my best to keep grinding every day.








my streak is bad
it might be because of timezones (you submitted your solution too late and it counted on the servers as the next day due to cf not knowing your time)
i checked your calendar and it shows that you DID solve a problem on july 13th
might be a client side error
Codeforces operates strictly on MSK or UTC depending on the specific extension you use. If you solve a problem late at night in your local time, it might already be the next day according to the server. This leaves a blank space on the previous calendar day breaking the streak. BTW YOU ARE DOING GREAT :)
Although you solve problems everyday, you only solved 800 — 1000 ones. These problems won't improve your skill.
It's because you submit a problem that has been solved before, or maybe you submit just before or after the date is slightly changing
I agree I'm trying to do a similar thing and last I tried this say, "hack" it didn't count it :( so I did a quick problem before the day ended... It's weird though
