In Jainism there is no special “start date” for eating mango, but there must be right time, condition and method of eating it.

For a Jain shravak/shravika (layperson), you may eat ripe mango when:

1. Time of day

- Eat only in daylight, not after sunset. - Cut and eat it fresh, not long after cutting. - Do not use mango that is cut/kept from the previous day.

1. Type of mango

- Prefer ripe, sweet mango. - Avoid: - Unripe, very sour mango used in strong pickles (khatta achar etc. – often more for taste than for simple food). - Mango that is over‑ripe, fermented, or has worms/insects.

1. How to prepare

- Wash the mango well. - Cut it in clean daylight, check for any insects/worms. - Avoid mixing many things together (heavy mixtures, ice, old curd, etc.) – keep it simple and fresh. - Do not eat mango in the night, in darkness, or in places where insects gather on cut fruit.

1. Sect (Śvetāmbara / Digambara)

- For ordinary householders, both Śvetāmbara and Digambara traditions generally allow ripe mango as a normal fruit, with the above rules of: - Ahimsā (minimum violence), - Freshness, - No night‑eating. - Jain sadhus/sadhvis have much stricter rules, and what they accept will depend on their specific maryādā.

In short: You can eat ripe, clean, fresh mango in the daytime, cut and inspected just before eating, and never after sunset or if there is doubt of insects or fermentation.
