I think the difference would be a High Mass or a Low Mass. Of course there can be a Low Mass on Sunday but there is usually always a High Mass on Sundays.
A High Mass is chanted while a Low Mass is spoken.
There is a Gloria, unless it’s during Ember Days, it is a Feria Day, votive Mass, or a Reqieum Mass.
There is no Credo unless it is a First or Second Class Feast.
Also, unlike many OF Masses during the week, more often than not, there is no sermon unless it’s a first class feast. Some priests differ on this, but from my experiences of attending both OF daily Mass and EF daily Mass, is that the EF is much more focused on the Sacrifice of the Mass rather than on the readings and a homily/sermon, etc. I also find the EF daily Masses shorter, making them for practical for fitting in before classes, between classes, after classes, etc. I would love it if there were a restoration to early morning daily EF low Masses throughout churches in the city to make it easier for working people/students to attend daily Mass.
