It is a Romanian pre-Christian tradition to give those you care about on March 1 a mărțişor (martzishor): a red and white string from which a small decoration is tied, symbolizing strength and health for the year to come.
March 1 is the beginning of the new year in the old calendar used in both ancient Rome and in Dacia (which roughly corresponds to the territory of today's Romania).
March 1 symbolizes a new beginning and therefore gifting someone a mărțişor is a form of sharing and celebrating the mystery of life. And it is also a form of purification and renewal, leaving behind the Old and welcoming the uncertainty of the New.
The Renewal Ritual is not an abstract, weird thing. In fact, it can be found everywhere: an office party, going out with friends, celebrations and anniversaries, these are all practical ways in which people underline the separation from what it was, making room for new and hopefully better experiences.
