What's the difference between All Saints...

All Saints Day, celebrated by the Roman Catholic church (and now other churches) on November 1, is set aside to honor church members believed to have gone to heaven. All Souls Day, November 2, was created to commemorate those who died baptized but without having confessed their sins, and thus they are believed to reside in purgatory. Roman Catholic doctrine teaches that intercessions (prayers) by earthly church members can cleanse these departed souls and prepare them for heaven.
