"Pambu Panchangam" refers to a traditional Tamil almanac often used in southern India for festival dates, astrological timings (tithi, nakshatra, rahu/ketu, yoga, karana), muhurtham (auspicious times), and regional temple schedules. The 2003 edition would have contained that year’s daily details and regional observances—useful for historians, astrologers, cultural researchers, and anyone curious about how timekeeping and ritual calendars were practiced locally at the turn of the century.
