can I set due dates as a specified period of time.

For instance a project (like a recording session or a meeting etc) may start at a certain Time. like 10am. and finish at 2pm. how can I make a note of this so that the length of time is reflected in the calendar? not just populated at the due date?

Hi @Beckview Studios 

It's Mary from Planyway calendar for Trello

It won't be possible with Trello calendar as they only link to due dates. But you can get it with Planyway power-up. We show the card duration on both: all calendar views and all timeline options.
