Excel is treating the number 3 as the third day in its serial date calendar,
which is January 3, 1900.

To indicate that the 3 is an hourly entry enter it using 3:0, or if it's 3
minutes enter it as 0:03

I would be really grateful if someone could offer some help.

I have formatted a cell to accept the time format HH:MM, but when I type in
a value say 3 it converts to 00:00 instead of 03:00. Why is this?

Any help or assistance would be greatly appreciated.

Many thanks,

Simon.
