When there are two months of Adar, the holiday of Purim is observed in the second month, while the 14th and 15th days of the first Adar are known as Purim Katan. What is the nature of that "small" Purim? What are its laws? Take Ten to find out. 

Today's Ten is sponsored by the Brownstein family in memory of Florence Brownstein a"h, Feiga bas Moshe.
