Daf Yomi in October 2019 has a problem. It jumps from Meilah 22 on Oct 9 to Kinnim 23 on Oct 10 and from Kinnim 25 on Oct 12 to Tamid 26 on Oct 13. Actually, I think that Nida comes after Meila.
Thanks for your message. Hebcal uses the same schema as http://www.kosherjava.com/ - both are derived from a 1998 implementation in Lisp by Bob Newell
The Wikipedia article on קדשים describes Maimonides' ordering of the tractates which disagrees with our version.
In particular, Maimonides places Kinnim last (and we place it between Meilah and Tamid).
