The thinking time applies to each game of the tournament.
In correspondence chess each player has X days for 10 moves.
After every completed 10 moves the player gets another X number of days for the next 10 moves. Not consumed thinking time from a previous 10-day period will be credited to the next 10-day period.
Notice: Typically the players will execute not more than about one move per day in correspondence chess games.
There can be defined a time credit per move. This will be credited to the thinking time of the player after each move execution.
In quick chess each player has X minutes for the game.
There is no vacation in quick chess games. I.e. If you currently have vacation, your thinking time runs anyway.
