Short answer

Q1, Q2, Q3, and Q4 are the four quarters of a fiscal year, each lasting three months, used to track and report financial performance.

Key points

  • A year is split into four three‑month quarters.
  • Q1: Jan‑Mar, Q2: Apr‑Jun, Q3: Jul‑Sep, Q4: Oct‑Dec (calendar basis).
  • Companies report earnings and set goals by quarter.
  • Fiscal quarters may differ from calendar months for some firms.

Q1, Q2, Q3, and Q4 are the four quarters that divide a fiscal year into three‑month segments, providing a standard timeline for financial reporting and planning.

Calendar‑based quarters

When a company follows the calendar year, the quarters are:

  • Q1: January – March
  • Q2: April – June
  • Q3: July – September
  • Q4: October – December

Each quarter ends with a set of earnings releases, allowing investors to see how the business performed over the last three months.

Fiscal‑year variations

Not every organization aligns its quarters with the calendar. Some choose a fiscal year that starts in a different month to match seasonal cycles or industry patterns. The quarter labels stay the same—Q1 through Q4—but the actual months shift accordingly.

Regardless of the calendar used, the quarterly system gives a consistent framework for tracking progress, comparing results year over year, and planning future strategy.

Frequently asked questions

Why do companies use quarters instead of monthly reporting?

Quarterly reporting balances detail and workload, giving enough data to spot trends without the noise of month‑to‑month fluctuations.

Can a fiscal quarter be longer or shorter than three months?

Generally quarters are three months, but a company may have a short first quarter when it changes its fiscal year start date.

Do all industries follow the same quarter schedule?

Most follow the standard calendar quarters, but retail, agriculture, and some global firms may adopt different fiscal calendars to align with seasonal demand.
