The Gregorian year is the default, so there is nothing to turn on to use it. The configuration task is the reverse: confirming the setting or deciding to move to a standard or custom fiscal year. Here is how to find and review the fiscal-year setting in Setup before you change anything.
- Open the Fiscal Year setup page
In Setup, use Quick Find to search for Fiscal Year and open it under Company Settings. The page shows whether the org is on a standard fiscal year (the Gregorian-based option) or has custom fiscal years enabled.
- Read the current start month
For a standard fiscal year, check the Fiscal Year Start Month. If it is January, the org is on a fully Gregorian year. Any other month means the fiscal year departs from the calendar even though it still uses Gregorian-aligned quarters.
- Decide whether a change is justified
Only move off the Gregorian default if the company's financial year actually starts in another month or needs irregular periods. If December 31 is the year-end, leave the setting as it is and document that decision.
- Plan the switch for a clean break
If you must change it, schedule the change for the first day of a new fiscal year. Warn forecast and dashboard owners, and have replacement user quotas ready, because changing the fiscal year clears existing quotas.
Follows the Gregorian calendar year but starts on the first day of any month you choose, keeping twelve months and four three-month quarters.
The calendar month a standard fiscal year begins. Set to January for a pure Gregorian year; any other month shifts every fiscal period away from the calendar.
Lets you define non-Gregorian period structures such as 4-4-5, thirteen-period, or 52/53-week calendars, configured period by period from a template.
- Changing the fiscal year deletes existing user quotas, which then must be re-entered by hand.
- Formula functions like YEAR and MONTH always use the Gregorian calendar, so they will not match a non-Gregorian fiscal-year report filter.
- A custom fiscal year cannot have a start or end date that overlaps a year already defined with the Gregorian-year template.
- Switching mid-quarter can move opportunities between forecast periods; always time the change for the start of a new year.
