There are two remaining riddles somewhere in the Skytrain. You check all the other walls. Nothing. Where else could the remaining riddles be?

You look down and notice a folded piece of paper wedged between the seats. At first you don’t think anything of it, but then you decide to investigate. You unfold it and it seems to be some year-round events program for Jewel. You think to yourself, if you weren’t stuck on this Skytrain you’d love to go to any one of the events.

Scanning the program you notice that someone has circled four random event dates:

Sixth of January
Second of March
Fourth of April
First of November
