Erev Lag BaOmer

 

Tachanun:

Tachanun is omitted on Lag BaOmer. It is omitted beginning from Mincha of the 17th of Iyar [Erev Lag BaOmer].[1] 

 

When do the mourning customs cease?

The mourning customs cease to be practiced beginning from the night of Lag BaOmer.[2] One may hence listen to music, get married and recite Shehechiyanu from that time. Those accustomed like the Arizal do not take a haircut on lag BaOmer, until Erev Shavuos, and so is the Chabad custom. Those that continue the morning period after Lag BaOmer, are to re-continue the mourning customs beginning from the night of the 34th of the Omer, which is Motzei Lag BaOmer.

[1] Siddur Admur; 2^nd opinion mentioned in 493/5

Ruling of Admur in Shulchan Aruch and other opinions: The 1^st opinion Admur ibid records states that the mourning customs are followed during the night of Lag BaOmer up until after day break being that Lag BaOmer is the 33^rd day of mourning, and even on this day there were some students who died [and hence reached the grand total of 24,000 deaths]. The mourning customs end after daybreak of Lag BaOmer, being we always apply the rule of Miktzas Hayom Kikulo to the last day of mourning, as explained in Yoreh Deah 395/1. According to this opinion, from that time and onwards the mourning customs are no longer followed. [Admur ibid; Rama 493/2] According to this opinion Tachanun is recited by Mincha of Erev Lag BaOmer.

[2] 2^nd opinion mentioned in 493/5; Rebbe in Shaarey Halacha Uminhag 2/55 based on Siddur Admur that rules like this opinion

Ruling of Admur in Shulchan Aruch and other opinions: The 1^st opinion Admur ibid records states that the mourning customs are followed during the night of Lag BaOmer up until after day break being that Lag BaOmer is the 33^rd day of mourning, and even on this day there were some students who died [and hence reached the grand total of 24,000 deaths]. The mourning customs end after daybreak of Lag BaOmer, being we always apply the rule of Miktzas Hayom Kikulo to the last day of mourning, as explained in Yoreh Deah 395/1. According to this opinion, from that time and onwards the mourning customs are no longer followed. [Admur ibid; Rama 493/2] This however is only in accordance to the ruling of the Rama ibid that the last of the students stopped dying on the 33^rd day of the Omer. However according to the Michaber 493/2 the mourning custom fully apply up until the morning of the 34^th day of the Omer as in his opinion the last of the students died on the 34^th day of the Omer.
