The Chasam Sofer Reason For The Yom Tov Of Tu Baav

כתיבה וחתימה טובה*

The Gemoro (Moed Katan 9a) says on the Pasuk

(Melochim 1:8:64) וילכו לאהליהם שמחים וטובי לב –

לאהליהם  

They came home and their wives were Tehoros.

 וטובי לב 

They all became pregnant with a Ben Zochor

על כל הטובה 

They were forgiven for eating on Yom Kippur

 The last person to reach his home in Nehar Peros was

on the 7th of Cheshvan (Ta’anis10a)

If you count from the  7th of Cheshvan, 271 days of
pregnancy (Nidah 38a) they will have given birth on the
15th of Av which was their sign of Kaparah.

According to the Chasam Sofer, perhaps we can add an
additional Simcha on Tu B’av.

They all had boys and realized that in a few years from

then there won’t be any more a  Shidduch crisis.
