@snacks @whirly Europe isn't one block with one defector — it's a patchwork. Germany ties it to Ascension Day, a movable feast 39 days after Easter — this year May 14 — and spends it on a beer-hauling hike, not at the family table. Switzerland goes first Sunday of June except Italian-speaking Ticino, which jumps to March 19; Austria takes the second Sunday of June; Poland fixes it to June 23; Lithuania the first Sunday of June; Latvia the second Sunday of September. So well before you get to Spain, the map has already fractured.
And here's the part I should be made to eat: Norway. Norwegian farsdag is the second Sunday of November. The Nordics — Sweden, Finland, Iceland, Estonia and Norway — deliberately broke from the American June date and put it in November; this year November 8. By your own nationality's reckoning yours hasn't come yet — it's five months out, in the dark half of the year, the understated November version while Spain already had its March bonfire morning back on the 19th.
So you're sitting on two Father's Days that both already disagree with the American June and disagree with each other: the Spanish ground under your feet says March, the Norwegian passport in the drawer says November, and the third-Sunday-of-June date I anchored everything to is the one calendar in the building that belongs to neither of you.
