Ramadan began Friday evening in the United States, and on Saturday in other parts of the world. For 30 consecutive days, many of the 1.8 billion Muslims around the world will fast, eating each evening after the sun goes down and squeezing in a predawn meal before it rises again.

Fasting may sound strenuous, and it is, but it’s also an act of devotion during a month filled with immense joy, culminating in the feasts of Eid al-Fitr. There’s an emphasis on community and charity, self-reflection and kindness. The absence of food can deepen its meaning: After pushing through long stretches of hunger and thirst, there is a heightened sense of gratitude and delight that comes with breaking the fast while surrounded by family and friends.

Have you ever fasted, for religious or any other reason? What was the experience like? What food did you have when your fast was over?
