It looks like you meant Paryushan in 2025 (not 2925). As of today (August 21, 2025), here are the confirmed pravachan series in Mumbai during the current Paryushan period:

• Shrimad Rajchandra Mission Dharampur (SRMD), NSCI Dome, Worli, Mumbai

- Dates: Wednesday, August 20 – Wednesday, August 27, 2025 (Samvatsari on Aug 27 as per this event) - Speaker: Pujya Gurudevshri Rakeshji - Daily timings: Morning 7:30 am – 10:00 am; Evening 7:30 pm – 10:00 pm - Notes: Morning Snatra Puja followed by pravachan; evening spiritual programs followed by pravachan; Samvatsari day pravachan 9:30 am – 12:00 pm. ( srmd.org, connect.srmd.org, happeningnext.com, townscript.com)

• Ratnasundarsurishwarji Maharaj (Ratnapravah Pravachanmala) – Mumbai locations

- Ongoing pravachans in Mumbai were held through June 2025 across Santacruz, Andheri, Malad, Parle, etc.; the organizer updates venues and dates frequently. Please check their “Live Pravachan” page for current-day updates during Paryushan. ( ratnaworld.com)

• City context (useful for planning)

- Mumbai media note that all three Jain sects are observing Paryushan together this year, and civic arrangements (like slaughterhouse closures) reflect the observance window in the city. ( timesofindia.indiatimes.com)

Important clarifications about dates

• Different Jain calendars and local sangh practices can show slight variations. Some city listings mark Paryushan as Aug 20–27, 2025 (as per the SRMD Mumbai program above). Always verify with your local upashray/derasar for exact Samvatsari and daily pravachan timings. ( srmd.org, connect.srmd.org)

If you need the sect-wise festival windows:

• Shwetambar Paryushan: commonly observed this week in Mumbai (Aug 20–27, 2025) per the major city event above. ( srmd.org)
• Digambar Das Lakshan Parva typically follows after Shwetambar Samvatsari; local Digambar derasars in Mumbai (e.g., Walkeshwar, Malad) announce their daily pravachan schedules locally; please check their office/notice boards for the exact Mumbai timings this year. (Could not find a single consolidated official Mumbai-wide Digambar schedule online today.)

What I could not find

• A single, authoritative city-wide calendar listing every Mumbai upashray/derasar pravachan for 2025. Many sanghs post daily on their own boards or WhatsApp groups. I have given the large public program(s) with confirmed dates and timings, plus the live-updated pravachan page for Acharya Ratnasundarsurishwarji. ( srmd.org, connect.srmd.org, ratnaworld.com)
