Frequently asked questions
How do I stretch annual leave?
Bridge public holidays: booking the working days between a holiday and a weekend can turn 3 leave days into a 9-day trip, as the efficiency figure shows.
Does the return day count as a day away?
It counts as a calendar day but rarely as a usable one — that is why the calculator subtracts your travel hours separately.
