清明一般在公历4月4日至6日之间变动，并不固定在某一天，但以4月5日最常见。清明既是节气又是节日，清明节气在时间和天气物候特点上为清明节俗的形成提供了重要条件。清明节气，与岁时物候相关，常以指导农事，有天朗气清、春耕时宜之意；清明节日，是人们扫墓祭祖、慎终追远的日子；因为二者相融，让清明兼具自然和人文内涵。
清明，是二十四节气之一，春季的第五个节气。斗指乙，太阳到达黄经15°，便为清明。清明节气因为节令期间“气清景明、万物皆显”而得名。清明是反映自然界物候变化的节气，这个时节阳光明媚、草木萌动、百花盛开，自然界呈现一派生机勃勃的景象。中国南方地区，此时已呈气清景明之象；北方地区开始断雪，气温上升，春意融融。
