Answer

Ganesh Chaturthi and Samvatsari are on different days this year because they are based on different religious calendars and different tithi rules.

• Ganesh Chaturthi is a Hindu festival observed on Bhadrapad Shukla Chaturthi.
• Samvatsari is a Jain festival observed at the end of Paryushan, traditionally on Bhadrapad Shukla Chaturthi or Panchami depending on Jain tradition and calendar calculation.

So even if they sometimes fall near each other, they do not always fall on the same date.

Explanation

In Indian calendars, festivals are not fixed by the English calendar date. They depend on:

• Tithi — lunar day
• Sunrise rule — which tithi is present at sunrise
• Religious tradition — Hindu and Jain communities may apply rules differently
• Local panchang differences — calendars can vary by region

Ganesh Chaturthi follows the Hindu observance of Chaturthi tithi. Samvatsari is connected with the completion of Jain Paryushan and the sacred practice of Pratikraman, forgiveness, and Michhami Dukkadam.

Because of differences in tithi timing and calendar observance, the two can fall on different English calendar dates.

Spiritual Understanding

For Jains, Samvatsari is not just a calendar event. It is the most important day of inner purification in the year. On this day, Jains sincerely ask forgiveness from all living beings:

Michhami Dukkadam — “May the faults I have committed be forgiven.”

The focus is on:

• Repentance
• Forgiveness
• Self-discipline
• Reducing anger, ego, deceit, and greed

Takeaway

Ganesh Chaturthi and Samvatsari may appear close because both occur around Bhadrapad month, but they follow different religious traditions and calendar rules. That is why they can fall on different days in a given year.
