Fiscal year calculator

Fiscal (or financial) years rarely match the calendar. This tool tells you which fiscal year any date belongs to across common conventions: calendar January, UK April, the UK personal tax year starting 6 April, Australia’s July start, and the US federal October start.

It returns the fiscal-year label, its exact start and end dates, the total number of days, and how many remain. Always confirm your own jurisdiction’s rules before filing.
