[tkgtd]

I had the same issue and created a simple snippet with TextExpander for Start Times.

For example, when something starts today, on the keyboard I type in ",td" and this will fill in the word "Today" for the start date.

As it relates to this thread, for a start day of tomorrow, I created a snippet where when I type in ",tm" it types in "Tomorrow 6AM", thus not needed a script. If you aren't a keyboard person, then the script may serve you better.

Same applies on my iPad and iPhone since TextExpander also syncs to my iOS devices.
