Fiscal Calendar Calculator

How to use this calculator

Choose a calendar date, the first month of the fiscal year and whether your organization labels fiscal years by their starting or ending year.

Fiscal months follow Gregorian calendar months. Quarter boundaries are three months apart. Day counts include both boundaries and account for February 29. This does not infer a 4-4-5, 4-5-4 or 53-week retail calendar.

A worked example

With an April start and ending-year labels, November 2, 2026 belongs to FY 2027, Q3 and fiscal month 8. That fiscal year runs April 1, 2026 through March 31, 2027.

Why do two organizations label the same fiscal period differently?

Some use the starting calendar year and others the ending year. Select the convention explicitly; the underlying boundaries remain visible.

Which calendar and years are supported?

Use Gregorian dates from 1900 through 2100, with results inside that range. Most daily plans are limited to 366 dates; academic terms and sprint plans allow up to 731. Forms limit the number of entries to keep calculations responsive. Holidays and policy rules come from your inputs. Date-only plans ignore DST; tools with time-zone inputs use the browser's time-zone data and explicitly resolve repeated times. Calendar exports preserve date-only markers or exact timed events as appropriate. Calculations run only when requested, without background polling.

What happens to my dates?

Calculations run on your device. Saving a calculation is optional and keeps it in this browser. A setup link contains the dates and settings you entered; anyone with the link can read them. Use one tab per saved calculator. Clear saved data from Privacy & settings.
