This is a cheat sheet for azure function CRON expressions that are used by the TimerTrigger binding in azure functions.
Basic Syntax
The structure of the CRON expressions in Azure is:
{second} {minute} {hour} {day} {month} {day of the week}
Using Configuration
Instead of specifying the CROM pattern directly in the [TimerTrigger] attribute, you can give a config setting name. This is great for testing locally on a higher frequency than deployed.
