This is a system that seeks to create a Haftarah-like system for the reading of Psalms, linking their meaning to the meaning of the reading or the Shabbat of that day. Like the Haftarah system, there are special psalms for the Shabbatot leading up to and following the Ninth of Av, as well as specific psalms for Rosh Chodesh and the special Shabbatot. Unlike the Haftarah system, if two portions are read together or a special Shabbat occurs on a day when another reading is done, both psalms are read (since psalms are generally shorter and easier to read than prophetic texts.)
