It's only a speculation at this point - although it is nearly impossible for a Black Diamond Event to not take place around Chinese New Year because TpGS is happening in the following weeks.

The non-dupe event is expected to be found in "Rewards", so a player should be able to keep it for as long as he/she wants.
