Bible in Ramazan

An anchor person in one of the Ramazan TV programmes posed the question that on which night of Ramazan was the Anjeel e Muqqaddas revealed to Hazrat Eesa (A.S.)

 I wonder if anyone would know it exactly as even the day of the birth of Holy Christ (A.S.) himself is disputed and some hold it to be on the 6^th of January instead of the commonly believed 25^th of  December.

It would be interesting to know if in view of the significance and importance of the month of Ramazan any other holy book like Torah (to Hazrat Musa A.S.) and Zaboor (to Hazrat Dawood A.S.)  were also revealed during this holy month, and if so, on which nights?

Could someone more learned enlighten us on it, please.
