Answer

Masakshaman starts on the day you formally take the vow to begin it, usually with proper guidance from a गुरु, साधु, साध्वी, or a knowledgeable Jain elder.

Explanation

There is no single fixed universal date for Masakshaman. It can begin on an auspicious day chosen with guidance, depending on:

• your capacity and preparation
• the advice of your spiritual guide
• the tradition followed in your Jain community

Spiritual Understanding

Masakshaman is a serious tapa, so it should begin with sincerity, discipline, and clear resolve. The important thing is not only the date, but the भाव with which it is undertaken.

Takeaway

Masakshaman starts when you take the vow properly, not on one fixed calendar day.
