So there's actually all kinds of chastity challenges. The first is International Chastity Day, which is January 14. That's when men lock up until Valentine's day so they can give their woman (or man) a great time. Next is the mothers day challenge, which is where men lock up from mother's day to father's Day. They're all about 1 month challenges. But then comes the big 3. Locktober, NOvember, and Denial December. They're each one month challenges but there's no break in them.
