Quarter Calculator

Quarter Calculator is part of Toolspire and is ready as soon as this page loads. This is the January-to-December year. India’s April-to-March financial year is the fiscal-year page, where January is not Q1.

What you can do here

Calendar, named

The headline says Q1 2026, and the detail says January–March.

April is Q2 here

So it cannot be confused with the fiscal page.

The date must exist

31 February is rejected.

The sequence

How to use the Quarter Calculator

Worth knowing

  • Quarter Calculator on Toolspire: 15 January 2026 is Q1 2026.
  • Months 1–3 are Q1, 4–6 are Q2, 7–9 are Q3, 10–12 are Q4.
  • 1 April is Q2, not Q1, on a calendar year.
  • The Indian fiscal year calls April Q1. That label is a different page.

Four blocks of three months

A calendar quarter splits the January-to-December year into four. January, February and March are the first. April starts the second. 15 January 2026 is therefore Q1 2026, and 1 April 2026 is Q2 2026. Companies that close their year on 31 March use a different numbering, and that numbering lives on the Indian fiscal year page so the two Q1s are not the same sentence.
