Frequently asked questions
Is the end day counted?
Not by default: from the 1st to the 5th is a difference of 4 days. Tick “Count the end day” for 5 days, as with a holiday.
What is 31 January plus one month?
The last day of February – the 28th, or the 29th in a leap year. The calculator points this out.
Are leap years taken into account?
Yes. All calculations use the real calendar including leap years and daylight saving changes.
Can I count working days instead?
Yes – use the working days calculator, which skips weekends and public holidays.
