Tearing (Kri'a) on Seeing Temple Ruins

You must tear four vertical inches at the neck of your shirt (and jacket, too, if you wear one) when seeing the ruins of the Temple in Jerusalem for the first time in more than 30 days. You do not need to be close by; do kri'a even if you see the mosques that are on top of the Temple mount.
Note A woman should not tear her garment if it would result in her being immodestly exposed in public. Don't tear your garment on Shabbat, Jewish festivals, chol ha'moed, Rosh Hashana, and Yom Kippur. Do tear even on the afternoons before Shabbat and Jewish festivals.
