Yes, here’s a link to a page that has all of the Seasons, their Sundays, and the Holy Days.
There have been some seasons and feasts that have been dropped. Septuagesimatide has been dropped in the current calendar. This was the two-and-a-half weeks prior to Ash Wednesday, back when the fasting and penences were more severe, this season was to physically and mentally prepare the faithful for Lent. However, in the current calendar, the Paschal Triduum is its own liturgical season. The octaves of: Epiphany, Ascension, Pentecost, Corpus Christi, and The Sacred Heart have been dropped in the current calendar. The only remaining octaves are that of Christmas and Easter.
There was no season known as “Ordinary Time” back then, instead there were the Sundays after Epiphany and the Sundays After Pentecost/Trinity Sunday (Green would be worn during these periods, like today.) There was no cycle lectionary for Sundays and daily Mass, instead the readings were always the same; ie readings for the 1st Sunday in Advent were the same every year. There were also fasting days known as Rogation Days and Ember Days, where the faithful would fast and pray against natural disasters and for a plentiful harvest. These are just some differences I can name off the top of my head.
