From Śrīla Jīva Gosvāmī’s «Laghu-vaiṣṇava-toṣaṇī» commentary on the Tenth Canto of Śrīmad-Bhāgavatam, 10.45.3. I have added the corresponding chapters of the Tenth Canto of Śrīmad-Bhāgavatam, the original sanskrit and approximate ages in parentheses. I have used Purīdāsa Mahāśaya’s edition of the commentary («Śrī Śrī Saṅkṣepa-vaiṣṇava-toṣaṇī», Mymensingh, 1946, sanskrit).

In His sixth year He was immersed in herding the cows – (ṣaṣṭhe go-cāraṇa-kautuka-mātraṁ)

[Note: Śrīla Jīva Gosvāmī says in the commentary to 10.24.1 that these līlās are described in Śrīmad-Bhāgavatam out of chronological order because of Śukadeva Gosvāmī’s lack of self-control due to his prema (prema-vaivaśyāt) and also because of the similarity of the pastimes (svajātīyatvāc ca)]

Nice post, Brijabasi Prabhu. It reminded me of one of the appendices from Sivarama Swami’s latest book, Nava-vraja-mahima. The following excerpt is from an appendix titled “Deliberation on the Ages of Krsna and His associates,” in which Maharaja addresses (among other things) the timeline you’ve posted here. Isn’t it surprising that Krsna started herding the calves at age two, or that he danced with the gopis at age eight?
Here’s the excerpt (edited for length):
That Kåñëa’s nava-yavana age and qualities fully manifest themselves in Våndävana leads one to the conclusion that He left for Mathurä in His fifteenth year. And Rüpa Gosvämé’s analysis of Kåñëa’s three primary ages as being five years each confirms that conclusion. Çrémad-Bhägavatam, however, says that Kåñëa lived in Våndävana for only eleven years before leaving for Mathurä. By that account He left Våndävana at the beginning of adolescence, not the end.
Çré Uddhava says to Vidura:
“Thereafter, His father, being afraid of Kaàsa, brought Him to the cow pastures of Mahäräja Nanda, and there He lived for eleven years like a covered flame with His elder brother, Baladeva.” (SB 3.2.26)
…Accepting that both statements must be correct, it is justified to wonder, “Is there a way to reconcile the two different ages?”
Luckily, Jéva Gosvämé has given a hint. In discussing the five-year periods given for each of Kåñëa’s three ages, the äcärya says, “This is a general description. Kåñëa should be understood to be special.” (Durgama-saìgamané 2.1.309)
And to our further good fortune, Viçvanätha Cakravarté Öhäkura further elaborates on this subject. He explains that Uddhava has correctly measured Kåñëa’s stay in Vraja at eleven years, but within that time the Lord progressed through each age at an extraordinary pace—fifty percent faster than a normal human being does—to reach nava-yauvana. In other words, it took only ten years for Kåñëa to reach the point of maturity that others reach at fifteen. (Särärtha-darçini 10.45.3)
