FAQ

How are the quarters divided?

Based on the calendar year (starting in January): Q1 is Jan-Mar, Q2 is Apr-Jun, Q3 is Jul-Sep, and Q4 is Oct-Dec. Note this differs from an April-starting fiscal year, which many Japanese companies use.

I need quarters for an April-starting fiscal year instead.

For the April-starting fiscal year and quarters commonly used by Japanese companies, use the Fiscal Year Calculator instead. This tool calculates calendar-year (January-starting) quarters.

Does "days remaining" include today?

Yes. It counts the number of days from the entered date (inclusive) through the last day of that quarter.
