Halocho #1285 - Is tomorrow a fast day?

In a non-leap year the 13th of Adar is Ta'anit Esther.

In leap years - like this year 5774 - תשע"ד - we fast and celebrate Purim in Adar-II.

However, in Adar-I we mark the 14th and 15th as "Purim Katan".

One should eat a bigger meal to increase happiness on 14th of Adar-I. Even in "walled cities" where Shushan-Purim is celebrated (e.g. Jerusalem) this is done on 14th (not 15th) of Adar-I. 

During Adar-I the Megila is not read, nor does one say עַל הַנִּסִּים.
