  1. Sh"t Yabea Omer 4:13 writes that one doesn't say Tachanun in the davening right before a siyum just like the mishna in Taanit (31a) says that in they made a holiday on Tu BeAv because certain families finished for the season the mitzvah of chopping wood for the Bet HaMikdash. see: http://dailyhalacha.com/Display.asp?ClipID=596
