I would like HubSpot to support a hard validation rule between two date properties. The rule should prevent users from saving a record if one date is earlier than another date (for example, “End date cannot be before Start date”).
Today, HubSpot only allows validation on a single date field in relation to the current date (such as “cannot be in the past” or “must be in the future”), but not in relation to another date property. This means users can still enter inconsistent data, like a project start date that is after the project end date, and the system will accept it. I do not want HubSpot to calculate or change dates automatically; I only want the system to block saving when the entered date is earlier than a specified other date on the same record.
