usually the calendar starts on the 1st and goe until the last day of the month....this time its from the 2nd to the 26..th giving us absolutely no margin at all. we have exactly 25 days to open 25 doors so we cant even miss 1 day!
Look on the challenge page in the game and click on the calender it's already there but it will not start to april 2nd. It says it will end on May 3rd
Exactly: you can start it any time before April 26, 11:59, but you have longer than that to complete it. The idea is that if you are going to be purchasing keys with GF or UN points you can wait until the very latest and buy your keys needed to complete it when you are at your highest level and get more XP for opening doors. You cannot start the calendar on May 3 at 11:50 and finish it 9 minutes later, which would give you the most xp per key.
