I don't know how to change the default...

You can however type 1 P to get 1:00 PM

or type 13:00?

or you can enter the values in a helper column and have a formula adding 12
hours in your main column...

Currently Excel defaults to AM when entering a time. Does anyone know if I
can make default to PM when entering a time I know should be after 12:00pm?
I can't figure out how I can let Excel know I mean 1:00 PM rather than 1:00
AM without typing in the PM.
