"Ramadan starts tonight, dear," a friend of mine told me this afternoon, and we commiserated briefly about the challenges of fasting, especially from smoking, for her.
It wasn't until later, when I was planning dinner (lucky lo mein noodles!), that it occurred to me that the Lunar New Year also starts tonight. And a little while after that? I realized that it's Mardi Gras, so Lent starts tonight, too. Such a convergence delighted me, and I had to find out how rare it was.
A little research revealed that the last time these three events intersected was 1863. Somehow, I don't think many people back then were in a position to even realize such a coincidence; the world was divided into much more homogeneous places, religiously, at least.
The next time? It will be 2189, and by then, maybe the world will be down to celebrate together.
