Uttara Bhadrapada is nakshatra number 26 of the 27 lunar mansions in Vedic astrology, spanning 333.33° of the zodiac in 13°20' steps. Its planetary lord is Saturn and its presiding deity is Ahir Budhnya.
The Moon's position in Uttara Bhadrapada at birth shapes the Vimshottari Mahadasha sequence — a Uttara Bhadrapada birth begins life in the Saturn mahadasha, with the balance of that period decided by how far the Moon had travelled through the nakshatra.
