iPhone 9.3 Calendar

There is no setting, but when you tap and hold on a specific date, for example, in the monthly view, a new, blank event will be created under your finger. If you let go, a detail window will open so you can complete all fields, but the date is already pre-filled with the date that you selected. Is that not working for you?

I think I understand what you are saying Curtjacobs.. I am thinking that is the same issue (one of them) that I am having:

I successfully added some appointments yesterday for future dates, but last night I was trying to look at a date in April to move an appointment to, and it wouldn't let me open that date, UNLESS I actually went into the appt. I wanted to move and picked a date in there and moved it. Then I tried to adde a different appointment TWICE (at least) to the current day (which was yesterday 3/29) at a later hour, so it would remind me of something, and I entered it and it disappeared. Never could get it to add.

This is a workaround, not a fix. This is clearly a bug. When adding it should open at the date you select no matter what view you are in.
