| Q2 | April – June | 3 months |
| Q3 | July – September | 3 months |
| Q4 | October – December | 3 months |

Business and finance revolve around quarterly cycles — from tax filings to profit tracking. The Quarter Calculator makes it easy to determine where each date fits in your reporting period.
Our quarter calculator helps you instantly determine which quarter a specific date falls into. You can check calendar quarters (Jan–Dec) or find fiscal quarters based on custom financial years like April–March, July–September, or October–September. It’s ideal if you’re searching for which quarter is this, quarter in a year calendar, or quarter start date and end date.
Use this tool to view calendar quarter dates, including Q1, Q2, Q3, and Q4 start and end dates. It answers common questions such as when did this quarter start, what calendar quarter is April, October which quarter, and previous or next calendar quarter from today. You can also calculate quarter beginning and ending dates for any year quickly.
This fiscal quarter calculator supports non-standard financial years, such as fiscal year starting in April, June, July, or October. Easily find fiscal quarter from date, check what financial quarter is it right now, or calculate fiscal quarters between two dates. It’s useful for accounting, payroll, reporting, and compliance-related queries.
You can also calculate the number of quarters between dates, find the previous quarter for a calendar year, or determine what quarter was 12 quarters ago. Whether you need quarter dates from today, next calendar quarter, or quarterly date month calculations, this quarter calculator provides fast and accurate results without manual counting.
