Hey @PZimathies this is possible with operations Hub and workflows. What you want to do is enroll contacts with your initial date/time property as a trigger. So let’s say the date property is “time of meeting”. You can create a custom property for “2 hours before time of meeting” or whatever you want.
You enroll when this property is known, then you can use operations hub to use the “format data” action to subtract 2 hours from that initial property and copy the datetime into your new custom property.
You can then use this new custom property in a new workflow to trigger whatever actions you wish to use!
Something like this:
