1. Byzantine Catholics normally begin the season with Forgiveness Vespers on Monday while Roman-rite Catholics begin on Wednesday with the administering of ashes.
2. The weekdays of the great Lent are aliturgical. During the week we have different services like vespers and the Presanctified Liturgy of St Gregory on Wednesdays and Fridays. This 'communion service' can only be performed by a priest and is just as long as a normal divine Liturgy. A text of this Liturgy (with some Catholic changes) can be found here.
3. One of my favorite portions of the Presanctified Liturgy is when we make profound bows and sing "Let my prayer rise as incense before you, and let the lifting up of my hands be an evening sacrifice." The Byzantine Lent is filled with prostrations and profound bows.
4. Byzantine Catholics sing Alleluia during Lent! This can be quite shocking to a Roman-rite Catholic. It has never disturbed me because the music style tends toward the minor keys, so it is a solemn alleluia.
5. I always miss the Roman-rite Easter vigil. 28 years ago or so, my family entered the Church during this Mass. This is really the only day of the year I wish I could visit a different church, but this week is the busiest of the year besides Christmas. It just isn't possible to get to another Mass. So, if you are Roman-rite, enjoy this Mass for me!
6. Here is a link from a Ukrainian Byzantine Catholic Church. Scroll down until you get to the descriptions of Holy Week and Easter. I couldn't say it better myself, so I won't. There's some great information there.
7.The fasting guidelines are stricter in the Byzantine rite, but can be changed with the guidance of a spiritual father. But I've talked about that until I am blue in the face...I have got to go soak some beans. ;)
