If your pious boss looks tuckered out this morning, he was probably out late remembering Jesus' Last Supper. And if he's really quiet this afternoon from one to three, it's probably not something you did: he's reflecting on the supposed time of the crucifixion.

The most significant weekend of the Catholic year is already upon us, and you'll be forgiven if you haven't found the perfect Easter hat just yet. Easter's date is based on a lunar schedule, and it won't come this early in our calendar again until the year 2160.

Despite the parish closings, you don't usually have to go very far in Boston to find a Catholic church. You could spend tonight remembering Christ's passion (Good Friday) at the epicenter of Boston Catholicism--the Cathedral of the Holy Cross in the South End (with fellow blogger Cardinal Sean, at 7 p.m., in Spanish.) If you're trying to abstain from meat, there's a great no-frills seafood place across the street.

Very lengthy Easter vigils will abound on Saturday night. John Kerry's spiritual home--the Paulist Center--is steps from the State House, and will start theirs at 8 p.m. Say an extra prayer for the casino bill.

Most churches will be packed on Easter Sunday, so get there early if you don't want to be standing in the back and looking guilty while the priest reminds people that his church is open every week. The famed Boston Boy Choir will sing at 11 a.m. services at St. Paul's off Harvard Square.

If you're looking for something closer to home, check out the archdiocese's parish directory.
