# MOD

Returns a remainder after a number is divided by a specified divisor.

## Use

`MOD(number, divisor)` and replace number with the field or expression you want divided; replace divisor with the number to use as the divisor.

![Scheduling Example](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-platform-extend_click-264-0-0-production-enus/5f7d9219-b7b1-4552-8891-f1aba9b289fc/images/icon_example.png)

Scheduling Example

`MOD(3, 3)` returns 0

`MOD(4, 3)` returns 1

`MOD(123, 100)` returns 23

To prevent users from scheduling meetings on a Saturday or Sunday, use a validation rule to apply a custom date field called My Date.

`CASE(MOD(My_Date__c - DATE(1900, 1, 7), 7), 0, 0, 6, 0, 1) = 0`

This example displays the following error message when the value of My Date is not Monday through Friday: “My Date is not a weekday.”
