Yea that's why I used Halloween, Xmas/winter Holiday, Easter/Spring and possibly one in the summer.

Contests will be very open, or at least they should be so that anyone can participate no matter their background. I noted eater and xmas as that's when those events will take place, so late dec and mid april.

If anyone has any suggestions for Summer, other than holidays, they'd be most welcome. Or on another point ideas for winter and easter they'd be kindly accepted too.
