If you are new to tradition, you may not be familiar with the Ember Days . Here is how we are to observe them this week (and throughout the year)
"The Wednesday, Friday and Saturday following the first Sunday in Lent, Whitsunday (Pentecost), Holy Cross day (Sept. 14), and St. Lucy's day (Dec. 13), which are days of fasting for the special sanctification of the four seasons, and for obtaining God's blessing on the clergy, for whose ordination the Ember Saturdays are specially set apart." (Catholic Dictionary) Note that ember days are of very ancient origin (possibly dating back to apostolic times). It is customary to fast and observe partial abstinence (meat once only) on Ember Days, and observe the usual Friday full abstinence.
