What if I'm going on vacation?
If you're going on vacation, you don't want to worry about your games timing out. Therefor every player gets 14 vacation days each year. If you are a Master you get 21 vacation days, and if you're a Grandmaster you even get 28!
When you request a vacation day, 24 hours will be added to the 'grace left' of each game you are playing at that moment. So it will last 24 hours longer before your 'grace left' will reach zero and you will lose the game. Of course, if you request more days, your grace will be upped by 24 hours per day. If a game starts during your vacation, the remaining part of your vacation will be added to its grace time as well.
On January, 1st, your vacation days will be reset to its original value again.
