Fiscal Quarter and Fiscal Year Calculator

How to use it

1. Type the Date you want the quarter of.
2. Type the First month of the fiscal year, from 1 for January to 12 for December.
3. Read Quarter and the fiscal year. Name the year as your accounts do: by the year it ends or by the year it starts.
4. Use Quarter starts and Quarter ends for the dates, or open the table for all four quarters.

How the quarter is found

A fiscal year runs for twelve months from its first month. Its first quarter is the first three months, the second quarter the three after them, and so on. The quarter of a date is found by counting the months from the first month of the fiscal year to the month of the date, and dividing the count by three.

Naming varies. The Wikipedia article on fiscal years says that fiscal years are often named after the calendar year in which they end, and that financial years are designated by the calendar year of the second half of the period (Wikipedia: Fiscal year). Some organisations name them after the year in which they start, so both names are shown.

Months into the fiscal year = (month of the date − first month + 12) mod 12
Quarter = whole part of (months into the fiscal year ÷ 3) + 1
Fiscal year starts: the first day of the first month
Fiscal year ends: the last day of the month before the first month, a year later

What this calculator does not include

• Fiscal years that start on a day other than the first of the month, such as 52 or 53 week years.
• Short or long fiscal years, such as a transition period between two fiscal years.
• The rules of a particular organisation. The month you type is the one your accounts use; check it against your own records.
