Reply To: when’s the last time for kiddush levanah?

(29 days, 12 hours, 793 chalakim)/2 from the previous Molad. In other words 14 days, 18 hours and 396.5 chalakim from the previous Molad. The Molad for Tamuz was Wednesday evening 5 minutes and 7 chalakim after 6. 14 days later was the entire night of Tes Vav Tamuz. If you haven’t said it yet, you missed the zman.
