[Avodah] No Gehenom on Rosh Chodesh

[SBA]

You learn something new every day...

The Chido in his peirush Pesach Einayim on Mesechta RH mentions
that just as neshomos are freed from Gehenom every Shabbos - so it is  
every Rosh Chodesh.

He cites the Mordechai in Arvei Pesochim, which indeed writes this.
(I suppose some will now be wishing for 3 days RCh...)

The interesting thing is that he also writes that on Yom Tov there 
is no such relief...
