Quarter Finder
Which quarter is this date in?
The calendar quarter for any date, its start and end, how many days it has, and how far through it you are — plus the same for the next four quarters.
Questions people ask
The things that come up about quarter finders, answered plainly.
How long is each quarter?
Q1 is 90 days, or 91 in a leap year; Q2 is 91; Q3 and Q4 are 92 each. They are not equal, which is worth remembering before comparing quarterly figures directly.
When does Q1 end?
31 March, on a calendar-year basis. On a fiscal calendar it ends three months after your fiscal year starts — use the fiscal quarter calculator for that.
