About the Quarter Calculator
The Quarter Calculator shows which quarter of the year a date falls in. It reports the calendar quarter from Q1 to Q4 along with the exact start and end dates of that quarter.
Because many organisations use a fiscal year that does not start in January, you can set the fiscal-year start month. The tool then shows the matching fiscal quarter and the fiscal year it belongs to.
It also counts the day of the quarter, the total days in the quarter and how many days remain, which is useful for reporting, planning and deadlines. Everything runs locally in the browser.

Frequently asked questions
- What quarter is a given month in?
- Calendar quarters group three months each: Q1 is January to March, Q2 is April to June, Q3 is July to September and Q4 is October to December.
- How does the fiscal quarter work?
- Set the month your fiscal year begins. The tool counts three-month blocks from that month, so a fiscal year starting in April makes April to June the first fiscal quarter.
- What does days remaining count?
- It counts the number of days left in the calendar quarter after the selected date, based on the quarter's true start and end dates.
