[1] At first, Mizrahi Jews would add dirges (kinnot) for the destruction only on the three sabbaths that are between the Seventeenth of Tamuz and Tisha B'Av, and not on weekdays.
[citation needed] After discussions that questioned this practice of mourning specifically on the Sabbath, it was decided to discontinue the recitation of the kinnot on these days.
[citation needed] Rabbi Isaac Luria canceled the customs of mourning on the Sabbath but declared that the Tikkun Chatzot should be said each and every day.
[citation needed] The Shulchan Aruch 1:3 states, "It is fitting for every God-fearing person to feel grief and concern over the destruction of the Temple".
[3] Sephardi communities in Jerusalem have a custom to sit on the floor and recite Tikkun Chatzot after halakhic midday during The Three Weeks.
[8] The Magen Avraham method (also held by Rebbe Nachman of Breslov) is that midnight is six clock hours after nightfall (appearance of 3 medium stars).
The Tikkun Rachel service is concluded with the reading of Isaiah 52:2, "Shake thyself from the dust..." A shorter version is usually printed in Sephardic siddurim that does not include the "Prayer of the afflicted," and has fewer kinnos.
