If the date is today, the [90 days ago](https://www.teampredict.ai/tools/date-calculator/90-days-ago) page gives the answer for today's date. The [date calculator](https://www.teampredict.ai/tools/date-calculator) takes a question in plain words, such as 90 days before January 31 2027 or 10 days before Nov 3, and the [days between dates calculator](https://www.teampredict.ai/tools/days-between-dates-calculator) counts the gap between two dates.

## Here are five questions about 90 days before a date, answered.

What is 90 days before a date?

Count back 90 days from the date, with the date itself as day zero. For example, 90 days before Thursday, December 31, 2026 is Friday, October 2, 2026.

Is 90 days prior to a date the same as 90 days before it?

Yes. 90 days before a date, 90 days prior to a date and a date minus 90 days all ask for the same day. For Thursday, December 31, 2026, all three give Friday, October 2, 2026.

Does 90 days before a date count the date itself?

No. The date you pick is day zero, the next day back is day 1 and day 90 is the answer, so the answer is counted and the date you pick is not. If a policy or contract counts the date you pick as day 1, the answer moves one day later, to Saturday, October 3, 2026 for Thursday, December 31, 2026.

Is 90 days before a date the same as 3 months before it?

No. For Thursday, December 31, 2026, 3 months before it is Wednesday, September 30, 2026, which is 92 days away, while 90 days before it is Friday, October 2, 2026. Three calendar months run from 89 to 92 days, depending on which months they are.

Can I type the date as 1/31/2027 or January 31 2027?

The date field above uses your device's date format. To type the whole question in words, such as 90 days before January 31 2027 or 90 days prior to 1/31/2027, use the question box on the date calculator.
