Hindu festival calendar, 1840
Every major festival's date for Delhi, calculated from the actual positions of the Sun and Moon rather than copied from a fixed yearly table, so the date you see here accounts for your own observance rules (tithi, paksha, and the specific moment of day each festival is anchored to).
