atha ca yāvan nabho-maṇḍalaṁ saha dyāv-āpṛthivyor maṇḍalābhyāṁ kārtsnyena sa ha bhuñjīta taṁ kālaṁ saṁvatsaraṁ parivatsaram iḍāvatsaram anuvatsaraṁ vatsaram iti bhānor māndya-śaighrya-sama-gatibhiḥ samāmananti.
The sun-god has three speeds—slow, swift, and moderate. The time he takes to complete a full circuit of the spheres of heaven, earth, and space at these three rates is spoken of by the learned under five names: Saṁvatsara, Parivatsara, Iḍāvatsara, Anuvatsara, and Vatsara.
According to solar astronomical calculations, each year extends six days beyond the calendar year, and according to lunar calculations, each year is six days shorter. Therefore, because of the movements of the sun and moon, there is a difference of twelve days between the solar and lunar years. As the Saṁvatsara, Parivatsara, Iḍāvatsara, Anuvatsara and Vatsara pass by, two extra months are added within each five years. This makes a sixth saṁvatsara, but because that saṁvatsara is extra, the solar system is calculated according to the above five names.
This verse states that a ‘year’ is the time in which the Sun completes its full course along with the celestial sphere, and that the year is described with different names based on the Sun’s varying speed.
He explains that Vedic tradition recognizes subdivisions or classifications of the yearly cycle according to the Sun’s slow, fast, or regular movements, hence multiple technical names for the same annual time span.
It encourages awareness that time is an objective, governing principle in creation, inspiring disciplined living and spiritual urgency—using one’s limited time for dharma and bhakti.
