Quarter Calculator

With the fiscal start on January, Q1 covers January to March, Q2 covers April to June, Q3 covers July to September, and Q4 covers October to December. This is the default and matches how most people talk about the four quarters of the year.

A fiscal year can begin in any month rather than January. Set 'Fiscal year starts' to that month and the quarters are renumbered from it, so an April start makes April the first month of Q1 and the following March the last month of Q4.

When a fiscal year starts later than January, its final quarter naturally spills past December. An April fiscal year, for example, ends its Q4 in January to March of the following calendar year, so the tool prints that later year next to those months.

The Year and Month boxes start on today's date, so the tool already shows the current quarter when the page loads. Change the fiscal start if you want that same month expressed against a non-calendar year.

No. A quarter is determined entirely by the month, so any day within a month falls in the same quarter. The tool asks only for the year and month for that reason.

Enter the calendar year in which your fiscal year begins. That year labels the fiscal period, and the tool adds a year automatically to any months that carry over into the next calendar year.

Yes. The Copy button puts a single tidy line on your clipboard, for instance Q2: April to June 2025, which drops cleanly into a spreadsheet, email, or planning document.

The month is chosen from a dropdown so it is always valid, and the fiscal start is likewise a menu. If a value ever falls outside the allowed range the tool shows a short message instead of a wrong quarter.

No. The quarter and its month span are worked out entirely in your browser, so no dates are uploaded or stored anywhere.
