Chaand Raat (Bengali: চাঁদ রাত , Hindi: चाँद रात, Urdu: چاند رات literally, Night of the Moon) is a Hindi, Urdu and Bengali locution used in Pakistan, India and Bangladesh for the eve of the Muslim festival of Eid ul-Fitr; it can also mean a night with a full moon.

Chaand Raat is a time of celebration when families and friends gather in open areas at the end of the last day of Ramadan to spot the new moon, which signals the arrival of the Islamic month of Shawwal and the day of Eid. Once the moon is sighted, people wish each other Chaand Raat Mubarak ("Have a blessed night of the new moon") or Eid Mubarak ("Blessings of the Eid day"). Women and girls decorate their hands with mehndi (henna), and people prepare desserts for the next day of Eid and do the last round of shopping.

In India, Republic Day commemorates the date on which the Constitution of India came into force replacing the Government of India Act 1935 as the governing document of India on 26 January 1950.^[1]

The 26th of January was chosen to honour the declaration of independence of 1930. It is one of the three national holidays in India. While the main parade takes place in the national capital, New Delhi, at the Rajpath before the president, the anniversary is also celebrated with varying degrees of formality in state capitals and other centres.
