Error message: The end shift must be later than the start of the s

[Ronnie]

I've wanted to make a 24 hours working schedule and make 2 shifts. THe first
shift would be 7:00am to 7:00pm and the second shift would be 7:00pm to
7:00am. But when I try to change the working time i keep on receiving this
message.

Hello Ronnie,
In the MS Project calendar, a shift can't overlap midnight. So you'll have
to set 3 shifts such as the following :

00:00 to 06:59
07:00 to 18:59
19:00 to 23:59

If you are setting these shifts to manage different resource groups, you'll
have to set 2 calendars : one for each shift.
