Jai Jinendra.

“Satamā?” is a casual Jain way (especially in Gujarati/Hindi families) of asking, “Are you fasting today on Satam?” Satam is the 7th lunar day, often observed with upvās or ekāsan.

How to reply, simply and politely:

• If you are fasting:

- Gujarati: “Hā̃, satamā upvās chhe.” - Hindi: “Hā̃̃, aaj Sātam ka upvās hai.” - English: “Yes, I’m observing the Satam fast today.”

• If you are not fasting:

- Gujarati: “Nahĩ, aaje upvās nathī.” - Hindi: “Nahĩ, aaj upvās nahin.” - English: “No, I’m not fasting today.”

If you’re doing a specific niyam, you can add it:

• “Ekāsan karũ chhũ.” / “Aaj main ekāsan kar raha/rahi hoon.” / “I’m on ekasan today.”
• “Beyāsan” or “Upvās” as applicable.

End respectfully if you wish: “Jai Jinendra.”
