Trello Calendar times

[Jason Joseph Newton]

Hi. I'm managing an event and though I have confirmed dates, the times are not confirmed, so I would like to just have an 'All Day' option until I can confirm. Any suggestions?

Hi, 

You can create a drop down type custom field  named "Time". 

Associate 2 options : confirmed / to confirm

You can assign particular color for each option for more visuel effects on the front of the card.
