Questions and answers
Should I include the end date?
For “how many days until” questions, no: from today to tomorrow is 1 day. For periods where both days count, like a holiday from the 1st to the 10th (10 days), tick it.
Are public holidays removed from working days?
Only Saturdays and Sundays are removed. Public holidays differ by country and region, so subtract the ones that apply to your deadline.
How are months added to a date?
The day of the month stays the same. If that day does not exist, for example 31 January plus one month, the last day of the month is used: 28 or 29 February.
