Naw-Rúz is the Bahá’í calendar festival that begins on the same day as Nowruz.
Naw-Rúz is the first day of the Bahá’í year and follows the Bahá’í month of fasting. The festival is linked historically and linguistically to the Persian New Year, although Bahá’í observance gives it a distinct religious meaning within the Bahá’í calendar.
The Bahá’í calendar uses nineteen months of nineteen days, with intercalary days inserted before the final month. Its New Year begins at sunset following the vernal equinox, with the exact timing determined according to Bahá’í calendar rules.
The spelling Naw-Rúz reflects Bahá’í transliteration conventions. It should not be confused with Ridván, the Bahá’í festival commemorating Bahá’u’lláh’s declaration, which is the religion’s holiest festival period.
