What quarter is…
How it works
A calendar year is divided into four quarters of three months each. Q1 runs January through March, Q2 April through June, Q3 July through September, and Q4 October through December. Companies, investors, and analysts use quarterly periods to report earnings, track sales targets, and compare performance year on year — because three-month blocks are long enough to show trends but short enough to act on quickly.
Not every organisation follows the calendar year. In the UK, the fiscal (tax) year runs from 1 April to 31 March, so Q1 is April–June, Q2 July–September, Q3 October–December, and Q4 January–March. Switch the toggle above to see fiscal quarters instead. Other countries use different start dates — for example, the US federal government's fiscal year begins on 1 October, while many US companies align with the calendar year.
Enter any date and Clockr identifies the correct quarter, labels it with the relevant year, and shows the exact start and end dates of that quarter. The tool also counts how many days have elapsed since the quarter began and how many remain until it ends — useful for deadline planning, budget tracking, and knowing where you stand in the reporting cycle.
Frequently asked questions
What are the calendar quarters of the year?
In the standard calendar year, Q1 is January–March, Q2 is April–June, Q3 is July–September, and Q4 is October–December. Each quarter covers exactly three months, though the number of days varies because months have different lengths and Q1 may include 29 February in a leap year.
What is the UK fiscal year and how does it differ from the calendar year?
The UK fiscal year for tax and government accounting runs from 1 April to 31 March. Its quarters are shifted accordingly: Q1 is April–June, Q2 July–September, Q3 October–December, and Q4 January–March. A date in February 2026, for instance, falls in Q4 of the fiscal year ending 31 March 2026 — not Q1 of the calendar year.
What quarter is it right now?
This page defaults to today's date, so the result updates automatically when you load it. Click the "Today" button in the quick-reference section to reset the date field, or toggle between calendar and fiscal year to see both interpretations.
When does Q1 start in the UK tax year?
Q1 of the UK fiscal year begins on 1 April and ends on 30 June. This is the first quarter of the tax year that runs through to 31 March of the following calendar year. For example, Q1 of fiscal year 2026 runs from 1 April 2025 to 30 June 2025.
How many days are in each quarter?
Calendar Q1 has 90 days in a common year or 91 in a leap year (because of 29 February). Q2 always has 91 days, Q3 has 92, and Q4 has 92. UK fiscal quarters follow the same month groupings, so the day counts are identical — only the quarter labels and year assignments differ.
Why do businesses report results by quarter?
Quarterly reporting gives stakeholders regular updates on company performance without the noise of monthly figures or the lag of annual reports. Regulators in many countries require listed companies to publish quarterly earnings. It also helps teams set seasonal targets, compare year-on-year growth, and align budgets with predictable three-month cycles.
What fiscal year does the US government use?
The US federal government's fiscal year runs from 1 October to 30 September. Federal Q1 is October–December, Q2 January–March, Q3 April–June, and Q4 July–September. This differs from both the calendar year and the UK April–March fiscal year. Many private US companies still use calendar-year quarters for their own reporting.
