42 days leave every year, you can break up to blocks of 6 days, at the end of each block a day off is always granted adding up to a total of 7 days... Depending on your bid and your luck you can easily add up to 5 to 6 days before or after the leave, it is not unusual. Counting on that to live a commuting life will probably make your experience frustrating at QR, but there are people doing it.
