# Calendar management strategies

The term **calendar** is used for the standard set of dates and time periods associated with a credit cycle. These include the due date, real due date, and cycle closing date. For more information, refer to [Credit cycle dates and time periods](https://developers.pismo.io/pismo-docs/docs/statement-cycle-dates).

Their are two types of calendar management strategies available for use with your programs and accounts.

* **Fixed due date**—This is the default calendar management strategy. The due date is fixed, and the Pismo platform uses it to calculate the cycle closing date. The [Fixed due date calendar management strategy](https://developers.pismo.io/pismo-docs/docs/fixed-due-date-calendars) guide explains how to create due date objects for a program and assign them to accounts.
* **Program calendar strategy**—This is an alternative type of calendar strategy that doesn't use a program due date object. The following program calendar strategies are available.
  * [Fixed cycle closing](https://developers.pismo.io/pismo-docs/docs/fixed-cycle-closing-calendar-management-strategy)—Cycle closing date is fixed, and the Pismo platform uses it to calculate the due date.
  * [Monthly cycle closing](https://developers.pismo.io/pismo-docs/docs/monthly-cycle-closing-calendar-management-strategy)—Specify the cycle closing date as either a day of the month or an "nth" weekday of the month, and the Pismo platform uses it to calculate the due date. A single cycle can span multiple months from 1 to 12.
  * [Monthly due date](https://developers.pismo.io/pismo-docs/docs/monthly-due-date-calendar-management-strategy)—Specify the due date as either a day of the month or an nth weekday each month. The Pismo platform derives the cycle close date backward from the due date. A single cycle can span multiple months from 1 to 12.
  * [Weekly cycle closing](https://developers.pismo.io/pismo-docs/docs/weekly-cycle-closing-calendar-management-strategy)—Cycle closes on a specific weekday every n weeks. The Pismo platform derives the due date forward from the cycle close date.
  * [Weekly due date](https://developers.pismo.io/pismo-docs/docs/weekly-due-date-calendar-management-strategy)—Due date falls on a specific weekday every n weeks. The Pismo platform derives the cycle close date backward from the due date.
  * [Daily cycle closing](https://developers.pismo.io/pismo-docs/docs/daily-cycle-closing-calendar-management-strategy)—Cycle closes every n days. The Pismo platform derives the due date forward from the cycle close date.
  * [Daily due date](https://developers.pismo.io/pismo-docs/docs/daily-due-date-calendar-management-strategy)—Due date falls every N days. The Pismo platform derives the cycle close date backward from the due date.

<Callout icon="🚧" theme="warn">
  Once you assign a program calendar strategy to an account, it's not possible to revert the account back to using the default strategy. However, you can use a program calendar strategy to reproduce the behavior of the default strategy. For more information, refer to [Reproducing the behavior of the fixed due date strategy](https://developers.pismo.io/pismo-docs/docs/reproducing-the-behavior-of-the-fixed-due-date-strategy).
