Pick a start date, then add or subtract a number of days, working days, weeks or months: the date appears at once, on the calendar too, with the weekends and public holidays of the period.
Days are counted from the day after the start: 14 days from Tuesday 3 November is Tuesday 17 November. For a stay, where the arrival day counts, open the options or pick the situation.
Questions
What date is 90 days from today?
Type today's date (it is already there), keep "+ add", type 90 and keep "days". Days are counted from tomorrow, so 90 days from 1 November is 30 January.
How are working days counted?
Monday to Friday, minus the national public holidays of the chosen country. 5 working days after a Friday is the next Friday.
How long is a month?
Months go date to date: 15 November plus 2 months is 15 January. From the 31st, a shorter month ends on its last day: 31 January plus 1 month is 28 February.
Is 90 days the same as 3 months?
No. Three months are 89 to 92 days depending on the months. When a rule says 90 days, count in days.
