What this tool does
Free fiscal year calculator that turns any calendar date into its fiscal year and fiscal quarter for whatever fiscal calendar your organisation runs on. Set the start month and the tool shows the FY label such as FY2025, the quarter from Q1 to Q4, the day number within the fiscal year, how many days are left, and the exact start and end dates of that fiscal year. The label follows the convention almost everyone uses: a fiscal year is named after the calendar year in which it ends, so a US federal year that begins on 1 October 2024 is FY2025. Built-in presets cover the calendar year, the US federal year that starts in October, the UK and India year that starts in April, and the Australian year that starts in July, and you can set any of the twelve months for a custom corporate calendar. One click copies a plain-text summary, and the shareable URL reproduces the exact date and start month. Everything runs in your browser; nothing is uploaded.

Real-world use cases
Tag an invoice or expense to the right fiscal year
Finance closes the books on a fiscal calendar, not the calendar year. A receipt dated 12 November lands in a different FY depending on whether the company starts in October, April or July. Drop the date in, set your start month, and the tool tells you the FY label and quarter to write on the coding line, so the expense files under FY2025-Q1 instead of being booked into the wrong period.
Confirm which quarter a deadline falls in
A grant report is due "by the end of Q2" and you run an April fiscal year. Is that September or December? Enter the deadline date with the April preset and read the quarter directly. No mental arithmetic about how the fiscal calendar offsets the calendar quarters, and no risk of preparing the wrong quarter's numbers.
Work out the exact start and end dates of a fiscal year
You need the precise window for an audit pull or a year-over-year comparison. Rather than counting on your fingers, enter any date in the target year and the tool prints the start and end, for example 1 October 2024 to 30 September 2025 for the US federal FY2025. Copy those dates straight into the query or the spreadsheet filter.
Track progress through the fiscal year
Halfway through a budget cycle you want to know how far along you are. The day-of-fiscal-year and days-remaining figures show that today is, say, day 211 of 365 with 154 days left, which is the kind of denominator a burn-rate or run-rate calculation needs. Share the link so the whole team reads the same position.
Translate between two organisations on different fiscal calendars
A partner reports on a July year and you report on October. The same transaction sits in different FY labels for each side. Run the date through both presets, note the two labels, and you can reconcile the numbers without arguing about which FY2025 anyone means.
Common pitfalls
Assuming the fiscal year is named after its start year. The near-universal convention names it after the year it ends, so a year starting October 2024 is FY2025, not FY2024. Mixing the two conventions across teams is the single most common source of fiscal-year confusion.
Reusing calendar quarters as fiscal quarters. With an April start, the calendar Q1 of January to March is fiscal Q4, not Q1. Reporting "Q1 numbers" without saying whose Q1 sends the wrong three months of data.
Forgetting that the fiscal year can span a leap day. A year that includes 29 February has 366 days, so a day-count or progress percentage built on a flat 365 will drift by one day. The tool uses the real length of the year your date falls in.
Privacy
Every calculation — the FY label, the quarter, the day count and the start and end dates — is plain JavaScript that runs in your browser tab. The date you enter and the start month you pick never leave the page and nothing is logged. The one caveat: the shareable URL encodes the date and start month in the query string, so a link pasted into chat will record those values in the recipient server's access log. For a sensitive internal date, use the copy button and paste the text rather than sharing the URL.
