How to use
1
Days vs working days
The simple difference counts every day, including weekends. For working days only, use the Working Days Calculator. The inclusive option adds one to the total — useful when counting "how many days are we away on holiday" if both arrival and departure day count.
2
Months and years
Months are calculated by walking the calendar month-by-month — so 1 January to 1 February is exactly 1 month, regardless of whether February has 28 or 29 days. Years work the same way. The "remaining" days are everything left after the months are counted.
