Mumbai to Celebrate Rare 12-Day Ganeshotsav in 2026 After Nine Years

Ganeshotsav in Mumbai is set to span 12 days in 2026 instead of the standard 10-day duration, marking a rare calendar occurrence that last took place nine years ago in 2017.

The extended celebration is caused by the alignment of tithis in the lunar calendar. The festival will begin with the arrival of Ganesh Chaturthi on September 14, 2026, and conclude with Anant Chaturdashi on September 25, 2026.

According to the lunar calendar calculations, the specific tithi alignment creates a 12-day window between the start of the festival and the final day of immersion. Extended festival periods of this nature are considered unusual occurrences in the festival calendar.
