Map any date onto your organisation's financial year: the FY label, the quarter, the accounting period, how much of the year has elapsed and exactly when it starts and ends.

Everything is calculated locally — your dates stay on your device.
Set the month and day your financial year begins — including 6 April for the UK tax year.
See both the fiscal quarter and the 1-12 accounting period a date falls into.
Days elapsed, days remaining and the percentage of the year completed.
Tell the calculator when your financial year begins and it maps any date onto it.
A fiscal year is simply a bookkeeping convention: a twelve-month window over which results are measured, budgets set and taxes assessed. Governments and companies pick starting points that suit their cycles rather than the calendar, which is why the same date can be in three different financial years depending on whose books you are looking at.
The US federal year starts in October, the UK corporation tax year in April, Australia and Japan in April and July respectively.
Fiscal quarters are counted from the fiscal year start, so a company with an October start calls October to December Q1, not Q4.
Larger finance teams talk in periods 1 to 12 rather than month names, because period 1 always means the first month of the year regardless of which month that is.
Retailers often use a 52- or 53-week fiscal year that always ends on the same weekday, so this month-based calculation is an approximation for them.
Questions about fiscal year starts, quarters and naming conventions.
A fiscal year is the twelve-month period an organisation uses for accounting and budgeting. It does not have to match the calendar year, and many governments and companies deliberately start theirs in another month.
On 1 October. Federal fiscal year 2027 runs from 1 October 2026 to 30 September 2027, and is named after the calendar year in which it ends.
The UK personal tax year runs from 6 April to 5 April. The corporation tax financial year is different, running from 1 April to 31 March.
Conventions differ. The US federal government names the year after the calendar year it ends in, while Australian and Indian practice usually writes a span such as FY2026-27. This calculator lets you pick either.
Most choose a quiet point in their trading cycle so that stocktaking and audit do not collide with peak trading. Retailers commonly end in late January or early February for exactly this reason.
