I'm just translating Anapanasati sutta into Serbian and in the introductory part there is an interesting expression:
"sāvatthiyaṃ komudiṃ cātumāsiniṃ āgamessāmī"
"I will stay in Savatthi until komudi full Moon day of the fourth month"
If "komudi" is name od the full moon in the month of kattika, does that mean that full Moon days in all other months have their names too?
