Hello @Mrshershey A Warm Welcome to our friendly King Community
I am sorry to hear that you have not received the Holiday Calendar event!!
If you have not seen the event within the first 3 days after it stated, unfortunately, this time you were not added to the group that have received the event!
One of the reasons for all the players not able to receive some of the events is that the King team wants to give the best experience to their players. For that, King releases an event to one group and different event to another group and no event at all to some other group of players!
