One can possibly bring a proof from the services on which one does not say tachanun. The practice is that on a day that one does not say tachanun, one also omits it on the previous minchah. This is not the case with Pesach Sheini. Although tachanun is omitted on the 14 Iyar, it is recited at minchah of 13 Iyar (see &ldquo;Luach l&rsquo;Eretz Yisrael&rdquo; by Rav Tuchachinsky). In the case of Pesach Sheini, the service prior to the afternoon of 14 Iyar is shacharis, and in accordance with the practice to also omit tachanun on the service prior to a specific occasion, it is omitted at shacharis of 14 Iyar.</span></span></span></p> <p class="MsoNormal" style="margin: 0cm 0cm 10pt;"><span style="mso-ansi-language: EN-US;" lang="EN-US"><span style="font-family: Times New Roman; font-size: small;">&nbsp;</span></span></p>
