It is customary for Orthodox Jews to immerse before Yom Kippur, and married women sometimes do so as well. In the customs of certain Jewish communities, men also use a mikveh before Jewish holidays; the men in certain communities, especially hasidic and haredi groups, also practice immersion before each Shabbat, and some immerse in a mikveh every single day. Although the Temple Mount is treated by many Orthodox Jewish authorities as being forbidden territory, a number of groups permit access, but require immersion before ascending the Mount as a precaution.
