the "Tachanun" prayers and the passages "E-l erech apayim"
and "Lam'natzeach" should not be recited. It is also forbidden to recite
eulogies ("hesped") or to fast on this day, and it is customary to engage

does not, however, insert the "Al Hanissim" into the prayers and blessings.
One is permitted to hold a wedding [on the fifteenth], since we do not
read the Megillah on that day. However, on the day we read the Megillah
(that is, the fourteenth), which is the day on which the essential
dimension of the Purim celebration ("ikkar ha'simcha") takes place,
weddings should not be held because it is improper to mix one celebration
with another ("eyn me'arvin simcha be'simcha") (2).

Joshua conquered the Land of Israel in 1272 BCE), read the Megillah on the
