The Matsya Purana states that the Srimad Bhagavatam was written in the Saraswati Kalpa? Does the Devi Bhagavatam mention in which Kalpa was it written?
Yes it mentions. It was composed in the SArasvat Kalpa.
26-40. Vyâsa said :-- O King! Maharsi Nârada thus kindling knowledge in me, went away; I also thought over his words. On the banks of the river Sarasvatî, I composed this Devî Bhâgavat to pass away my time during the excellent period of Sârasvata Kalpa. This Purânam is excellent; it is composed on the authority of the the Vedas; all doubts are removed by it; many nice events are narrated here.
