I have created a simple form for taking bookings I need to be
alerted should i dupicate date information IE there is already a
booking on this date. if a formula is needed could the same formula
be used for times as well

IE already booked at this time, or already booked at his date

Possibly look at the techniques outlined at Chip Pearson's site:

Or try using Conditional Formatting:

If oyur dates were entered in column A, then select column A and open
Conditional Formatting from the Format menu.

with 'Formula Is' in the Conditional Format box, enter:
"=IF(COUNTIF(A:A,A1)1,TRUE,FALSE)" and change the format to yellow, or
whatever.

Now whenever you enter a date, it will change colour if it already
exists.
