About Fiscal Year Dates Calculator

A fiscal year starting in April runs from 1 April 2026 to 31 March 2027, so 4 September 2026 is day 157 and falls in Q2. Fiscal years vary widely - April in the UK and India, July in Australia, October for the US federal government - which is why cross-border comparisons must state the basis.

Formulas

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why do fiscal years not match calendar years?

Historical and practical reasons - the UK's April start descends from the old Julian new year, and agricultural or budget cycles drove others.

Does the fiscal year affect tax?

Directly. Income and expenditure are allocated to the fiscal year in which they fall, so timing decisions around the boundary matter.
