No. Christmas is a Christian festival, not a Jain festival.

In Jainism, major festivals include:

• Paryushan (Śvetāmbara) / Das Lakshan (Digambara)
• Mahavir Janma Kalyanak (Mahavir Jayanti)
• Diwali (commemorating Bhagwan Mahavir’s Nirvana)
• Kshamavani/Michhami Dukkadam (Forgiveness Day)
• Ayambil Oli and other penance-oriented observances

Jains respect people of all faiths, so some may exchange greetings, but Christmas is not part of the Jain religious calendar.
