yobta' yupma' is a holiday in Klingon culture, marking the end of the harvest. It is traditionally celebrated with a large feast shared with guests. On planet Pheben III, it is also celebrated by a fistfight tournament.

yobta' yupma' is primarily marked by farmers and natives of farming worlds, and is not widely known or celebrated by members of other segments of the Klingon Empire. (KE novel: A Burning House)

The glossary in A Burning House provides the translation of yobta' yupma': "the we-have-completed-harvesting festival".
