Anant Chaturthi falls on September 25, and the public banking schedule largely remains unchanged that day. According to NDTV, banks stay open across most of India despite the festival.

The holiday impact is limited to specific locations. NDTV reports that banks in Gangtok remain closed on September 25 due to the Indrajatra Festival, indicating a local holiday separate from the Anant Chaturthi observance.

Overall, the information available is that September 25 is not broadly observed as a nationwide bank holiday for Anant Chaturthi, but exceptions apply for Gangtok where a different festival drives closures. Readers in other regions are directed to follow local announcements for any further restrictions or branch-specific changes.
