The Holy Ashura, commemorating the martyrdom of Hazrat Imam Hussain (RA), will be observed in the country on July 29 as the Muharram moon was not sighted in the Bangladesh sky.
The holy month of Muharram will start on Thursday.
The decision was taken at a meeting of the National Moon-Sighting Committee held at the conference room of the Islamic Foundation at its Baitul Mukarram National Mosque office with State Minister for Religious Affairs Faridul Haque Khan in the chair on Tuesday.
On this day in the Hijri year of 61, Hazrat Imam, the grandson of Prophet Hazrat Muhammad (PBUH), along with his family members and 72 followers embraced martyrdom in the hands of Yazid's soldiers in the desert of Karbala to uphold the teachings of the Prophet.
The day is a public holiday.
Shia Muslims will bring out Tazia processions in Dhaka marking the day.
