Given that the site has 27,093 users, of which each one has precisely one birthday, and there are less than 27,093 days in a year, the calender is filled with birthdays. I didn't notice any events, just birthdays and bank holidays. Could birthdays be filtered out of the calender as they are of no use to most of the site's users. Instead putting event details in the calender. I know for a fact there are events I am interested in around my area, I just don't know about them yet!
