No Such Halacha

part 2

משנכנס אדר מרבין בשמחה

No such Halacha

 

 *. 

The Gemoro (Ta’anis 29a ) In the name of Rav

it was said, "the same way, when

the month of Av comes in, you reduce with Simcha,

so too when the month of Adar comes

in you add with Simcha".

The Rambam and Sh. Aruch bring the Halacha of

משנכנס אב ממעטין בשמחה

They do not** mention משנכנס אדר מרבין בשמחה

The obvious reason is, there is no such  Halacha

to be Marbeh B’simcha when Adar comes in.

The Chasam Sofer (O.Ch 160) explains the reason. 

"Since we don't Pasken like Rav that Aveilas starts on

Rosh Chodesh Av,(According to strict halacha it starts on

on Erev T.B.***), therefore we also don't Pasken

that Simcha starts on Rosh Chodesh Adar.

The Halacha in Sh. Aruch & Rambam of משנכנס אב ממעטין בשמחה 

applies to only one thing, not to build a

Binyan Shel Simcha. All other types of refraining Simchas like

eating meat, drinking wine etc. start only on Erev T.B.

On this halacha we can't say The same as when Av comes

in you are not allowed to build Binyan Shel Simcha-- so too

when  Adar comes in you may build a Binyan

Shel Simcha. Building  a binyan Shel Simcha may be done all year round not only in Adar.

There is no such Halacha of Marbim Besimcha for Adar whereas there is a 

Halacha in Rema to be Marbeh Ketzas Simcha on Lag Baomer.

It seems that a קצת שמחה mentioned in Shulchan Aruch is a greater שמחה

than a complete שמחה of משנכנס אדר that is not mentioned in Shulchan Aruch.

* According to the Shulchan Aruch & Rambam

** The Magen Avraham does mention it

***3 weeks, 9 days & Shavua Shechal Bo are Minhag
