Mahalaya, also known as Mahalaya Amavasya, holds immense spiritual and cultural importance as it marks the beginning of the auspicious Devi Paksha and the end of Pitru Paksha. It is observed seven days before Durga Puja and symbolises the descent of Goddess Durga to Earth from her heavenly abode. Mahalaya 2025 is on September 21. To celebrate the festival, share Subho Mahalaya 2025 wishes with Mahalaya greetings, quotes and messages.
