How to set a time filter in Zapier to prevent calls during business hours

I have a Zap where my CRM is the trigger — whenever a new lead comes in, it triggers my AI tool to make a call. However, I only want these calls to happen after hours (5 PM to 9 AM) and on weekends.

I’ve already tried using the Formatter to adjust the time and added Filters to restrict the Zap, but it still keeps triggering during business hours (between 9 AM and 5 PM on weekdays).

Can anyone help me figure out the correct way to set up the time filter so that my Zap doesn’t trigger during 9 AM to 5 PM on weekdays?

Thanks in advance!

I’ve set this up for several clients before - with formatters and filters is the way.

I’d need to see your setup to be sure (can you post some screenshots of the formatter and filter step) - but my first suggestion would be to check the correct timezone is set in your Zapier settings.

For the Formatter steps, change the From Time Zone to: US/Eastern

This is because the Input timestamp has a time zone offset (-05:00), which indicates the time zone is US/Eastern.

Updated to EST, it says your run passes the rules for the filter and continues running the zap

Try splitting the Filter conditions into 2 different filter steps.

1 to check the day from Formatter Step 2 with 2 OR condition.

  • [OUTPUT] contains Saturday
  • OR
  • [OUTPUT] contains Sunday

1 to check the hour form Formatter Step 3 with 2 OR conditions.

  • [OUTPUT] is less than 9
  • OR
  • [OUTPUT] is greater than 17
