First of all it is not 18:00PM. Miltary (24 hour time) does not use AM, PM.
If you want the hours between 7:00 and 18:00 to be day and the rest night,
and A1 contains the date and time, the it's simply

=IF(AND(MOD(A1,1)=VALUE("7:00"),MOD(A1,1)<=VALUE( "18:00")),"Day","Night")
or
=IF(AND(MOD(A1,1)=VALUE("7:00 AM"),MOD(A1,1)<=VALUE("6:00
PM")),"Day","Night")

I find that easy to understand

I need to convert the data from a cell that contains date and time to a
different cell that will give a result of day /night, which functions
should
I use and what will be their syntax?
if the hours i refere to as day are 7:00AM-18:00PM, and night
18:00Pm-07:00AM
thank you

the formula results: value and not d/n
how would u change it to express d/n with the original cell only includes
the "hour am/pm" ?
thanx
