Lag Ba-omer and Pesah Sheini

Blurry image of a bonfire and the words: Lag Ba-omer and Pesah Sheini

Pesah Sheini

One day of special interest that occurs during sefirah is Pesah Sheini (also spelled Pesach Sheni), the Second Passover, which falls on the fourteenth day of the month of Iyyar.

Coming a month after Passover, it was an opportunity in Temple times for those who had been in a state of ritual impurity during Pesah to offer a delayed version of the paschal sacrifice. Today, the day is marked solely by the omission of Tachanun in the Morning and Afternoon Services.

Lag Ba-Omer

And just a few days later on the eighteenth of Iyyar falls Lag Ba-omer, “the thirty-third day of the omer” (also spelled lag ba’omer or lag baomer).

Believed to be the day on which the plague that afflicted Rabbi Akiva’s students ceased, Lag Ba-omer is a day of respite from the sadness of sefirah. Tachanun is not said, weddings are permitted, and haircuts and shaving are allowed even for those who refrain from both during the sefirah weeks.

Kabbalists also observe this special day as the Yahrtzeit of Rabbi Shimon bar Yochai, and to this day many in Israel make pilgrimages to his grave in Meiron. To mark the fact that Lag Ba-omer is also said to be the anniversary of the revolt against Rome led by the students of Rabbi Akiva, the day is also observed in many Jewish schools as a field day.

Many communities celebrate Lag Ba-Omer with a communal bonfire and outside activities.

May a person be released from Omer restrictions (e.g. haircuts) before Shavuot if the opportunity arises without guarantee of its availability later?
