The Day of the Covenant is a Baha'i holy day in late November that commemorates the appointment of 'Abdu'l-Bahá as the Center of Baha'u'llah's covenant. This event is a celebration of unity, the continuity of divine guidance, and the covenant between God and humanity. The holiday is celebrated on the fourth day of the Baha'i month of Speech (Qawl), which typically falls on either November 25 or 26.
