Gyaras tithi means the 11th lunar day in the Jain lunar calendar.

In Jain tradition, it is also called Ekadashi. This tithi comes after Dashami (10th day) and before Baras/Dwadashi (12th day).

In Jain practice, tithis are important for:

• fasting
• pratikraman
• religious observance
• special vows and penance

So, gyaras tithi = ekadashi = the 11th day of the lunar month.
