The attribution to the Rema is in his Tshuvos Simon 5.

Just to add that the Minchas Elozor (as well as others) attribute this to
the Rambam see the Shaarei Yissachar Maamorei Chodesh Ador, Mamar Yimei
Soson ois 33 and Mamah HaShkolim ois 12. (I have also seen attribution
to the RaM (which could be either the Ramabam or the Rema) in many places
it is prefaced with "Mamar HaChochom". (I also saw an idea that connects
it to the Yosifun chapter 18 who says Ein Simcha Ksimchas HaNitzochon).
