"On Sundays during Lent are Catholics allowed to continue their sacrifices? For example, if someone gave up television for Lent and he did not want to watch television on Sundays either, would it be canonically incorrect for him to continue abstaining from this amusement? Or by the laws of the Church, should he make a point of watching television in order to show the observance of Sundays as not being days of fasting and penitence?"

Again we must distinguish. One thing is that historically the Church never classes Sunday as a penitential day; another thing is the range of healthy and wholesome voluntary sacrifices that many Catholics offer during Lent. Among other reasons, these sacrifices prepare for Easter, make reparation for failings and constitute an act of inner freedom from the attachments toward worldly things.

Because of the voluntary nature of sacrifices, a Catholic is under no obligation to leave them aside on Sunday and may freely observe them during the entire Lenten season.

Indeed, ascetically this is often the best thing to do, since interrupting these sacrifices can weaken the resolution to make it to the end. Some people, however, especially those imbued with a more liturgical spirituality, might find a Sunday interval to be helpful in living the spirit of Lent. It very much boils down to what each person considers as being most spiritually beneficial to his soul and for the good of others.
