Technically, yes. You won’t be committing a mortal sin if you skip the Evening Mass of the Lord’s Supper. Canon law is clear: only days listed in Canon 1246 are obligatory. Maundy Thursday isn’t on that list, even in countries where it’s a public holiday (like Italy or Spain).
But—and here’s the pastoral curveball—your local bishop might have given a dispensation or encouraged the faithful to attend. Some dioceses treat it as a "solemnity of the Lord" locally. So if your priest is acting like it’s a must-go, he’s not wrong in spirit, just in law. It’s a beautiful mess, isn’t it?

Real talk: Why does this even matter?
Because we live in a world of overstuffed schedules. If you’re juggling work, kids, and a mental load the size of a Prius, knowing whether you must attend Mass vs. should attend matters. I get it. Last year, I was exhausted on Holy Thursday, and the guilt almost outweighed the grace.
Here’s my two cents: if you can make it, go. The Mass of the Lord’s Supper is one of the most intimate, moving liturgies of the year—bare feet, a foot-washing priest, and a procession to the Altar of Repose that feels like a vigil with your best friend. It’s worth rearranging your evening for.
