Folk with kids might want to keep on eye on this one...its great when you get to the weekend and haven't planned anything

Its the evenmax website (which doesn't always have all the Helsinki events, but has many). Great to find bizarre things especially out west...like fire station open days, small town kids days etc
If anyone has found other ways of keep tabs of whats on for kids, you may want to post aswell.
