for or at ?

[Zoe2008]

we already booked the tennis for 08 March

we already booked the tennis at 08 March

which one is correct ? And the sentence is correct or not ?

 

[buggles]

We have/had already booked the tennis for/on the 8th of March. We would use either of the alternatives in any combination.
A native speaker would never use "at" except to say " we booked the tennis at half past two......."
