Two special events / 14th of Iyar
Pesach Sheni / Second Passover – for those that were impeded from bringing an offering on Passover – they had a second chance on Pesach Sheni (see the Torah gives a second chance 🙂 ) To commemorate this some people eat Matza.
And it is the Hilloula Celebration and Yartzeit of the Holy Tana Rabbi Meir Baal Haness. Light a candle in his memory and say a prayer to Hash-m that in his merit you will be answered.
