What makes Shekalim different? Note that the Gemara on these mishnayot is Talmud Yerushalmi, the so-called Palestinian Talmud. Why is it here? Also, the content of Shekalim makes its placement in Seder Moed incongruous, at least at first read. || Opening with the proclamation for people to contribute their shekalim (half shekel) to the Beit HaMikdash, for upkeep, repair, public welfare, and even communal sacrifice. Also, why this contribution was collected when it was? Plus: Breaking down reading Megillat Esther on the 15th, for the walked cities, with different content and language than we know from the Bavli, as commentary on the mishnah. Note that we don't do the Adar mitzvot in the leap month of Adar I, but only Adar II. Also, were the people on the cities supposed to read Megillat Esther for two days?
