National Revolution and Solidarity Day (Bengali: জাতীয় বিপ্লব ও সংহতি দিবস) is a commemorative and former public holiday celebrated in Bangladesh on 7 November to commemorate the 7 November 1975 Bangladeshi coup d'état (Sipahi–Janata Revolution) by regular army soldiers and the common masses that showed solidarity with them.

[1][4] Meanwhile, the soldiers proceeded to release Maj. Gen. Ziaur Rahman, who was put under house arrest at the inception of the coup by Mosharraf.

Abu Taher and his clandestine revolutionary socialist group of soldier mutineers, the Biplobi Shainik Sangstha (BSS), to unsuccessfully create a socialist revolution, resulted in Zia's ascension to power.

[13][14] 7 November was a national holiday in Bangladesh during the military government of Lt. Gen. Hussain Muhammad Ershad and prime minister Khaleda Zia's ministries.
