Here is another formula for you to consider (note that I used 16:00 for the
switch over between Day and Late)...

If A1 contains a time value only (e.g., 12:34)
**************************************************
=LOOKUP(ROUNDUP(24*A1,9),{0,8,16},{"Early","Day"," Late"})

If A1 contains a full date (e.g., 8/10/2008 12:34)
**************************************************
=LOOKUP(MOD(ROUNDUP(24*A1,9),24),{0,8,16},{"Early" ,"Day","Late"})

Can you calculate whether a time is between two other times to show early,
day or late shifts for example?
