56 calendars are a lot of arithmetic, and some of them rest on scholarship where careful people disagree. If a date looks wrong to you, we want to know — particularly if it’s a tradition you keep and we’ve rendered it poorly. And if there’s a reckoning we don’t carry, tell us; that’s largely how we decide what to add.
