There are about 7.6 billion people in the world. And around 24% of them -- 1.8 billion -- are fasting from sunup to sundown. Every day. For an entire month.
It's Ramadan, the holiest month of the Muslim calendar.
But what if you're not a Muslim -- just a caring, considerate person. Is there anything you should do so you don't come across as insensitive to your fasting friends in the US during Ramadan?
Short answer: No. Long answer: No.
But you can earn some cool points if you follow these 10 tips:
9. You can say 'Ramadan Mubarak' ...
There's no "war on Christmas"-level controversy surrounding the greeting (it means "Happy Ramadan"). Your Muslim co-worker will appreciate the thoughtfulness.
10. ... but please don't say, 'I should fast, too. I need to lose weight'
Ramadan's not about that. Plus, one of Ramadan's side effects is obesity (it's all that post-sundown overeating).
