Whats happened?

I played tiny zoo for a long 3 years and totally loved it back then. I stopped playing then because I got a new phone and everything was lost. Now, 2 years later I decided to play again. But what happened? Everythings messed up and not on chronological order. No updates or fun holiday events. Right now the game thinks its Valentines Day?!? Its actually Summer right now?! Loved the game back then but it seems lost now. Not sure if its worth playing again..!
