Birkat ha-Hammah (ברכת החמה, also: ha-Chamah, Hahammah, Hachammah), is Hebrew for "The Blessing of the Sun."

It is a special Jewish prayer recited once every twenty-eight years. According to the Babylonian Talmud (tractate Berachot 59b), it is said when the Earth returns to the same position relative to Sun that it had when the universe was first created. The prayer is traditionally recited outdoors at sunrise.

Order of the service

No set service existed until the Shulkhan Arukh; since then various similar religious services have been offered by Rabbi Moses Sofer, the Mishnah Berurah, and (for Conservative Jews) Lasker and Lasker. The service generally includes:

• Quotations about the sun from the Tanakh
• Four verses from the Tanakh which spell out the Tetragrammaton
• Some of Talmud Berakhot 59b
• Parts of Psalms 148 and 90
