After the eight days of paryushan at what time can we start eating food on the 9th day
On the 9th day after eight days of Paryushan, you break your fast in the morning after sunrise. The standard rule (Navkarsi) is to eat about 48 minutes after local sunrise, and only after completing morning purity practices (bath, stavan/paath, and samayik/pratikraman). Community calendars (Paran/Kaal) may also give a specific window published by your sangh, so follow that if your local group has announced one. In short: break your Parṇa in the morning, roughly 48 minutes after sunrise. If your sangh provides a fixed Paran Kaāl for that day, follow that exact timing. ( jainknowledge.com)
