Maun Ekadashi is not a recognized Jain observance. Ekadashi is a Hindu lunar-day vrata, and Maun Ekadashi (the day of silence) is part of Hindu ritual calendars, not a standard Jain festival.

In Jainism, silence (mauna) is an important ethical practice but is applied within Jain disciplines rather than as a separate festival. Key Jain practices involving silence include:

• Samayik (meditative, equal-ritual session) often conducted in a quiet, focused manner.
• Pratikraman (confession and reflection) which can involve restrained speech.
• Personal vows of restraint and discipline that emphasize avoiding improper speech and speaking truthfully and compassionately.

If you’re exploring how Jain traditions treat silence and related disciplines in more depth, a Jain-focused source may discuss how mauna fits with the vows (five mahavratas for monks and the other vows for lay Jains) and with regular practices like Samayik and Pratikraman.
