Every data quality rule and every source integration checks your data based on a specific schedule. This schedule can be fine-tuned with Cron Expressions to support any need.

Sifflet relies on Cron expressions to define schedules. If you are not familiar with Cron, this link is your starting point.

If you need more flexibility on when your rules should run - for example, scheduling your rules to run on a specific hour or weekdays only - you should create a new schedule with the right Cron expression and attach the right rules.


Time reference

The time reference is on UTC.
So a rule set up with a cron "0 9 * * *" will mean it will run every day at 9 am UTC time.
