The Hindu calendar is a traditional lunar calendar used in India for religious and cultural purposes. It is also known as the Panchangam or the Indian calendar. The Hindu calendar follows a 12-month lunar cycle, with each month based on the phases of the moon.

The Hindu calendar includes various festivals, auspicious dates, and holidays that are important to the Hindu community. Some of the major festivals celebrated in Hindu culture, such as Diwali, Holi, and Navratri, are based on the Hindu calendar.

The Hindu calendar also includes information on tithis (lunar days), nakshatras (star constellations), yogas (planetary combinations), and karanas (half-tithis), which are important for determining auspicious times for various activities and events, such as weddings, housewarming ceremonies, and other rituals.

Today, the Hindu calendar is available in both print and digital formats, and several online resources offer free downloads of Hindu calendars. These calendars often include detailed information on auspicious dates, timings, and events specific to the Hindu community, making them a useful resource for people following Hindu traditions and culture.
