Hey @CONeill7, thanks for reaching out!
From what I’m seeing, the Calendly integration with HubSpot will create an activity on the contact record. From there, I know that you can filter activities by name (like if the activity name includes “Calendly”), but I’m not sure if meeting date data comes into HubSpot (unless you’re sending it over through a custom question). You may also be able to check and see if there is a value for “Activity Date” since that may be the actual date of the meeting!
If you are passing this data from Calendly into HubSpot through a custom question, you can use a workflow to copy the data from Calendly into the respective HubSpot property (more info in this support article from Calendly).
Otherwise, I don’t believe that time/date-specific features are a native functionality (unless the Activity Date engagement property contains that info).
HubSpot Meetings is hands-down the best meeting tool to use with HubSpot. You may have some good reasons not to use it, but the tool has a similar feel to Calendly, is native to HubSpot (so it counts a booked meeting like a form submission and allows you to send reminder emails days/hours/minutes before a meeting), and fits right into HubSpot reporting. If you haven’t explored HubSpot Meetings before, I strongly encourage you to give them a shot!
Hope this helps!!
