How to Work Out a Date 30, 60 or 90 Days from Today

The quick answer

Open the Date Calculator, leave the start date as today, type the number of days and read the result with its weekday.

Calendar days vs business days

Contracts usually mean calendar days unless they say 'business' or 'working' days. Tick the business-days box to skip weekends; public holidays need checking separately because they vary by country.

Months are not 30 days

'One month from 31 January' has no exact answer; the convention is the last day of February. If precision matters, write deadlines as a number of days.

Does the start day count?

Usually not – day one is the day after. Check the wording of the agreement.
