โปสการ์ดดอกไม้ : Introduced by Pope Gelasus in 498, perhaps in response to a local Roman tradition of lovers writing their names on an urn in February

วันหยุดฆราวาส : The idea of an international women's day was first put forward at the turn of the 20th century amid rapid world industrialization and economic expansion that led to protests over working conditions. Women from clothing and textile factories staged one such protest on 8 March 1857 in New York City. The garment workers were protesting what they saw as very poor working conditions and low wages. The protesters were attacked and dispersed by police. These women established their first labor union two years later.
