In Jain context, “Pakhi” usually refers to Pakshik (fortnightly) vrat / observance – something done once each fortnight according to the lunar calendar, not the English month.

Your line “Pakhi in March” is a bit unclear because:

• Jain vrats like Pakshik Pratikraman, Pakshik Upvaas, etc. are fixed by tithis (lunar dates),
• While March is a Gregorian (English) month.
• So the exact dates of “Pakhi” in March will change every year based on the lunar calendar and local Jain Panchang.

If you tell your location and which year and which Pakhi (e.g. Pakshik Pratikraman / Upvaas / Paryushan-type Pakshik) you are asking about, a local Jain Panchang or temple will give you the exact tithis and matching March dates more accurately. In general, “Pakhi” means a Jain religious observance that repeats every fortnight according to the Jain lunar calendar.
