Children's Day is celebrated on various days in many places around the world, in particular to honor children. Major global variants include a Universal Children's Day on November 20, by United Nations recommendation.^[1] Children's Day is often celebrated on other days as well.

The World Conference for the Well-being of Children in Geneva, Switzerland proclaimed June 1 to be International Children's Day in 1925. It is usually marked with speeches on children's rights and wellbeing, children TV programs, parties, various actions involving or dedicated to children, families going out, etc.^[2][3] Official discourse in Turkey argues that Children's Day had its origin in Turkey. The Grand National Assembly of Turkey was established on 1920, April 23, and to commemorate the event, April 23 was proclaimed a national holiday in 1921. The founder of The Republic of Turkey,Atatürk, has given this day to the children.

Easter (Old English: Ēostre) or Pascha (Greek: Πάσχα, Paskha; Aramaic: פֶּסחא‎ Pasḥa; from Hebrew: פֶּסַח‎ Pesaḥ)^[1] is a Christian feast and holiday celebrating the resurrection of Jesus Christ on the third day after his crucifixion at Calvary as described in the New Testament.^[2][3] Easter is preceded by Lent, a forty-day period of fasting, prayer, and penance. The last week of Lent is called Holy Week, and it contains the days of the Easter Triduum, including Maundy Thursday, commemorating Maundy and the Last Supper,^[4][5] as well as Good Friday, commemorating the crucifixion and death of Jesus.^[6] Easter is followed by a fifty-day period called Eastertide or the Easter Season, ending with Pentecost Sunday. The festival is referred to in English by a variety of different names including Easter Day, Easter Sunday,^[7]Resurrection Day and Resurrection Sunday.

Easter is a moveable feast, meaning it is not fixed in relation to the civil calendar. The First Council of Nicaea (325) established the date of Easter as the first Sunday after the full moon (the Paschal Full Moon) following the northern hemisphere's vernal equinox.^[8] Ecclesiastically, the equinox is reckoned to be on 21 March (even though the equinox occurs, astronomically speaking, on 20 March in most years), and the "Full Moon" is not necessarily the astronomically correct date. The date of Easter therefore varies between 22 March and 25 April. Eastern Christianity bases its calculations on the Julian calendar whose 21 March corresponds, during the 21st century, to 3 April in the Gregorian calendar, in which the celebration of Easter therefore varies between 4 April and 8 May.
