The Skand Purana says Sati was born in the 1st Manvantar of the Pitri Kalpa which was the 30th Kalpa in the second Parardha of Brahma.
The text again says that Parvati was born in the Vaivasvat i.e. 7th Manvantar of the present Varah Kalpa.
Does this imply that the present Varah Kalpa is the 31st one or were there other Kalpas too in between? If there were what is the order of our present Kalpa in Brahma's second Parardha?**
EDIT: Vayu Purana Chapter 21 mentions 34 Kalpas:
The kalpas since the original creation were as follows. (1) Bhava. (2) Bhuva. (3) Tapah. (4) Bhava. (5) Rambha. (6) Ritu. (7) Kratu. (8) Vahni. (9) Havyavahana. (10) Savitra. (11) Bhuvah. (12) Oushika. (13) Kushika. (14) Gandharva. (15) Rishabha. (16) Shadaja. (17) Marjaliya. (18) Madhyama. (19) Vairaja. The great Vairaja Manu was born in this kalpa and his son was the great sage Dadhichi. (20) Nishada. The race of nishadas (hunters) were created during this period. (21) Panchama. (22) Meghavahana. The word megha means cloud and vahana means to bear. In this kalpa, Vishnu adopted the form of a cloud and bore Shiva on his back. It is thus that the kalpa received its name. (23) Chintaka. (24) Akuti. (25) Vijnati. (26) Mana. (27) Bhava. (28) Vrihat. (29) Shvetalohita. (30) Rakta. (31) Pitavasa. (32) Sita. (33) Krishna (34) Vishvarupa.
So then are we in the 35th Kalpa?
