Śrīmad-Bhāgavatam
[Canto 2, Ch. 10]
saptaviṁśo'tha vairājo gaurīkalpas tathāparaḥ māheśvaras tathā proktas tripuro yatra ghātitaḥ pitṛkalpas tathā cānte yaḥ kuhur brahmaṇaḥ smṛtaḥ
Therefore the thirty  kalpas  of Brahmā are: 1. Śvetakalpa, 2. Nīlalohita, 3. Vāmadeva, 4. Gāthāntara, 5. Raurava, 6. Prāṇa, 7. Bṛhatkalpa, 8. Kandarpa, 9. Savyotha, 10. Iśāna, 11. Dhyāna, 12. Sārasvata, 13. Udāna, 14. Garuda, 15. Kaurma, 16. Nārasiṁha, 17. Samādhi, 18. Āgneya, 19. Viṣṇuja, 20. Saura, 21. Somakalpa, 22. Bhāvana, 23. Supuma, 24. Vaikuṇṭha, 25. Arciṣa, 26. Vallīkalpa, 27. Vairāja, 28. Gaurīkalpa, 29. Māheśvara, 30. Paitṛkalpa.
These are Brahmā's days only, and he has to live months and years up to one hundred, so we can just imagine how many creations there are in  kalpas  only. Then again there are  vikalpas  which are generated by the breathing of Mahā-Viṣṇu, as is stated in the  Brahma-saṁhitā  ( yasyaika-niśvasita-kālam athāvalambya jīvanti lomavilajā jagadaṇḍa-nāthāḥ ). The Brahmās live only during the breathing period of Mahā-Viṣṇu. So the exhaling and inhaling of Viṣṇu are  mahākalpas , and all these are due to the Supreme Personality of Godhead, for no one else is the master of all creations.

O King, I shall in due course explain the measurement of time in its gross and subtle features with specific symptoms of each of them, but for the present let me explain unto you the Pādma-kalpa.
