Today is 7th of December, but when i solved a puzzle, I saw the 6th of December in my profile activity.
I get that, but the other way around. At 6 PM every day, Lichess turns the page to the next day! Every game I play in the evening is marked as being played the following day.
For me at around 1 or 2 PM every day lichess says that all of my activity after 1:00 or 2:00 PM was done on the next day.
That's because profile activity uses the server time, which is UTC. The current time in UTC at the time of this post is 11:52 PM Dec. 6.

Oh I never knew that
Yes, an interesting "bug" indeed!
