# Fixed cycle closing calendar management strategy

Use the [Create program calendar strategy](https://developers.pismo.io/pismo-docs/reference/createprogramcalendarstrategy) endpoint to create a **fixed cycle closing** calendar management strategy for a program. Set the `strategy` field to `FIXEDCYCLECLOSING`, and provide values for `cycle_closing_day` and `days_between_cycle_closing_and_due_date`. The platform uses these fields to calculate the due date.

Assign the new strategy to an account using the [Update account calendar strategy](https://developers.pismo.io/pismo-docs/reference/updateacountcalendarstrategy) endpoint.
