On the First Sunday of Advent, four Sundays before Christmas — so the Church's year opens in late November or early December, not in January.
Advent, Christmas, Lent, the Sacred Paschal Triduum, Easter and Ordinary Time. Ordinary Time is the longest, and falls in two stretches: between Christmas and Lent, and between Pentecost and Advent.
Green for Ordinary Time, violet for Advent and Lent, white for Christmas, Easter and most feasts of the Lord, Our Lady and non-martyr saints, and red for Pentecost, Palm Sunday, Good Friday and the martyrs.
They are ranks. A solemnity is the highest and keeps its own Mass with Gloria and Creed; a feast ranks below it; a memorial lower still, and an optional memorial may be kept or passed over at the priest's discretion.
A day on which the faithful are bound to attend Mass and to rest from work that would hinder it. Every Sunday is one, along with a handful of solemnities that vary by country.
