All Saints Eve.

...wish you a safe weekend.
*********************************Halloween, also known as Allhalloween,[6] All Hallows' Eve,[7] or All Saints' Eve,[8] is a celebration observed in many countries on 31 October, the eve of the Western Christian feast of All Hallows' Day.
It begins the observance of Allhallowtide,[9] the time in the liturgical year dedicated to remembering the dead, including saints (hallows), martyrs, and all the faithful departed.[10][11]

One theory holds that many Halloween traditions may have been influenced by ancient Celtic harvest festivals, particularly the Gaelic festival Samhain, which may have had pagan roots.
