Feast of ‘Aẓamat (Baháʼí Faith, day shifts with March Equinox, see List of observances set by the Baháʼí calendar)

The Baháʼí calendar used in the Baháʼí Faith is a solar calendar consisting of nineteen months and four or five intercalary days, with new year at the moment of Northern spring equinox. Each month is named after a virtue, as are the days of the week. The first year is dated from 1844 CE, the year in which the Báb began teaching.

The Baháʼí Faith is a religion founded in the 19th century that teaches the essential worth of all religions and the unity of all people. Established by Baháʼu'lláh, it initially developed in Iran and parts of the Middle East, where it has faced ongoing persecution since its inception. The religion has 5–8 million adherents spread throughout most of the world's countries and territories.

The March equinox or northward equinox is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere and cross the celestial equator, heading northward as seen from Earth. The March equinox is known as the vernal equinox in the Northern Hemisphere and as the autumnal equinox in the Southern Hemisphere.

This table is determined by when the March Equinox falls. It fell on March 20 from 2018 to 2021 and will fall on March 21 in 2022–2023. All Baha'i observances begin at the sundown prior to the date listed, and end at sundown of the date in question unless otherwise noted. The Birth of the Báb and Birth of Baháʼu'lláh fall on November 5–6 in 2021.
