All Hallows Eve, All Saints Day, All Souls Day (The Triduum of Hallowtide).
“Halloween” comes from “All Hallow’s Eve,” as it falls the day before the Solemnity of All Saints, a Holy Day of Obligation. The trio of All Hallow’s Eve (Oct 31), All Saints’ Day (Nov 1), and All Souls’ Day (Nov 2) is sometimes known as the “Autumn Triduum”.
Update: What does “Triduum” means?
It (Triduum) comes from Latin roots that mean, essentially, “the three days” or “period of three days” (tri- = three, -dies = days).
