Ok, so on March the 1st there’s a very old romanian celebration/tradition called Martisor ( the name is basically a diminutive of March/Martie)and women all over the country get this red and white string and they have to pin it to their clothes, somewhere close to their heart.
Later edit (because someone asked what it symbolizes):
There are some legends surrounding the red and white string: one of them is about Spring protecting a snowdrop from the cold of winter and hurting her hands in the process, other one is about a knight saving the Sun ( the Sun here is a beautiful girl ) from an evil dragon but historically I guess it comes from the Romans who were celebrating New Year on the first day of Spring ( this was also the month of the god of war which sorta explains the red ). Thracians also associated the color red with spring and the white with winter so the string can be associated with the two seasons.
Wow this post has reached 100 notes. I might make a habit of talking about Romanian traditions. :>
