Ayambil Tap is a Jain fasting/observance done in many places by different communities. There isn’t a single universal record that lists “the city where Ayambil Tap was done” for all events. Each temple, sangh, or family may note their own Ayambil observances, so the city you’re looking for would be tied to a specific temple or year.

If you want to preserve a record of where Ayambil Tap was done, you can keep a simple log with these details:

• Year and month (the specific tithi or festival during which Ayambil was observed)
• City
• Temple or sangh involved
• Names of the observers (if known)
• Duration (e.g., 7 days, 11 days)
• Source (book, diary, temple notice, or family record)

This makes it easy to “save” and search later for a particular Ayambil event.

If you have a specific event in mind (e.g., the Ayambil observed at a certain temple in a given year), share any exact hints you have (temple name, sect—Digambar or Shwetambar, or approximate year), and I can help narrow down how to locate or document that particular instance.
