Calendars are a pain to fill in. Software like Fantastical 2 can make it easier, but not everyone has it or wants to type out the same things each time they create an event.
Calendars SHOULD be more useful. They should remind you where, when, and what the event is, without you having to manually fill the information in.
I’ve created a workflow template that you can copy and edit. I use it to schedule my entire day at the press of a button on my iPhone.
My use case is that I work part time in an office— I press a button and it schedules the entire workday including location, commuting time, an extra event in the morning for my morning routine.
I also have a button for morning gym.
Here is the template.. Check it out, and reply if you have any questions on how it works.
