I'm trying to create a macro which allows me to input an event into fantastical and then create an event for travel 30 minutes before the beginning of that event (for 30 minutes) and an event for travel for 30 minutes following the event. Everything is working except for the time calculations before/after the main event. Is there a way of having KM +/- time from a date set as a variable?
I can't see how to make that work with a variable from a user input - 'ward visit date time is' where the variable which I want to add/subtract time from.
