We are using Odoo V13.0 Community Edition, and wanted to change the Accounting Period / Fiscal Year from the default "January - December" to "April - March" as per Indian accounting standards.

The documentation here mentions about this -https://www.odoo.com/documentation/user/13.0/accounting/overview/getting_started/setup.html#accounting-setup-periods

The "Note" section also refers to using the Configuration / Settings to change the period. However, when attempting to do so within our instance, there seems to be no editable field under the 'Fiscal Periods' section.

Please help!
