Wiosna - Marzanna ceremony?

Can anybody remind me of the Polish name for the first day of spring please? I know that there's an informal tradition amongst children in Poland to play truant on this day but that's all I know so cultural background is also welcome information. Dzieks.

en.wikipedia.org/wiki/Marzanna

The tradition of burning or drowning an effigy of Marzanna to celebrate the end of winter is a folk custom that survives in Poland, Slovakia and the Czech Republic. Typically taking place on the day of the vernal equinox, the rite involves setting fire to a female straw effigy, drowning it in a river, or both. In Poland, this is often performed during a field trip by children in kindergartens and primary schools

it's "Topienie Marzanny"...

Thanks guys. I was actually thinking of "Dzień Wagarowicza" but I appreciate the additional input.

looks like a bit of overmoderation, wouldn't you say? nice jumping the gun..

post as you please

yes, seems you guys did that here and couldn't be more off topic yet no edits to fix it...
