  Each site's celebration dates are calculated in advance according to a special combination of zodiacal positions of Bṛhaspati (Jupiter), Surya (the Sun) and Chandra (the Moon). The relative years vary between the four sites, but the cycle repeats about every 12 years. Since Jupiter's orbit completes in 11.86 years, a calendar year adjustment appears in approximately 8 cycles. Therefore, approximately once a century, the Kumbh Mela returns to a site after 11 years.
