How we add dates
Days and weeks are added on the calendar. Months and years keep the day of the month, and when that day does not exist we use the last day: January 31 + 1 month = February 28 (or 29).
Business days skip Saturdays and Sundays; public holidays are not excluded.
Frequently asked questions
What date is 90 days from today?
Enter today's date, choose to add 90 days and see the date and day of the week. The page opens with this example.
Is adding 1 month the same as adding 30 days?
No. A month goes to the same day of the next month (which may have 28 to 31 days); 30 days is always 30 calendar days.
Are holidays counted in business days?
No. Only Saturdays and Sundays are skipped. Adjust if there is a holiday in the period.
