3 Months from Today

A quarter of a year

Three months is one quarter, which is why it appears in business planning, probation periods, short leases and review cycles. In days it varies: three months span between 89 and 92 days (90 to 92 in a leap year), depending on the months involved.

Examples that show the difference

• From 1 December to 1 March is 90 days in a normal year.
• From 1 July to 1 October is 92 days.
• From 1 February to 1 May is 89 days in a normal year.

Starting at the end of a month

Starting on 30 November, three months later would be 30 February, which does not exist. The calculator uses the last day of February instead: the 28th, or the 29th in a leap year. The same clamping applies to every month that is shorter than the starting day.

If your plan counts days instead of months, use the 90-day page. The two answers are often one or two days apart.

Questions people ask

Is three months the same as 13 weeks?

They are close but not equal. Thirteen weeks is 91 days, while three months range from 89 to 92 days. For a plan that follows the calendar, use months. For a schedule built from weekly blocks, use weeks.

How is this different from a calendar quarter?

Calendar quarters start on fixed dates in January, April, July and October. Three months from today is rolling: it starts today and ends on the matching date three months later. Business reports often use calendar quarters, so be sure which one you mean.
