noun, noun which may take the genitive case particle 'no'
daily publication; daily issue
Refers to something published or issued daily, especially newspapers. Often used as a prefix or in compounds like 日刊新聞.
This newspaper is a daily publication.
I subscribe to a daily newsletter.
This sports newspaper is published daily.

日刊 means a publication issued daily, in contrast to 年刊 which is issued once a year, but the similar 〜刊 form makes the two easy to confuse at a glance.
