Thanks for pointing this out. I'll look how this can be fixed. Polish works similarly (21 maja 2020, maj 2020). However, when abbreviated month names are used, this is not an issue because abbreviated month names always have 3 letters, which is different for Russian.
I think - function MONTHS_EN can be translated to MONTHS_I18N with support many languages.
Check please this commit. And you must change you code for work with MONTHS_I18N.
P.S. I see conflict between my PR and your code.
