Birthday rituals are historical and universal events, which have been around since the prehistoric era. But in ancient history, only the privileged had birthdays; the "parties" were solely reserved for kings and nobility members.

Familiar birthday customs and symbols are currently seen among most cultures, however, some people have adopted unique traditions, characterized by their values and way of life.

For example, in ancient Japan, children often died young, so nowadays, in addition to their actual parties, they participate in the 7-5-3 celebration (Shichi-go-san), held on November 15. The name refers to the ages of the children celebrated: any child who reaches age three, boys who reach age five, and girls who reach age seven. They put on fine clothing and visit a religious shrine in thankfulness for their health.

Another interesting tradition is in Nepal, where it's considered good luck for the birthday girl or boy to have brightly colored rice yogurt smeared on their forehead. There may be cake, there may be gifts, but colorful, delicious, and sticky yogurt? Almost always.

Interestingly, ancient Greeks also celebrated their gods' birthdays. And we're having their "leftovers" even today. The Greeks had a tradition where they would bake a special cake made of wheat, honey, olive oil, and cheese. It was sometimes made into a lunar shape to honor the goddess Artemis. In honor of her beauty, candles were put on the cake to make it glow.

Over time, the birthday cake spread throughout the world. It is often thought that China was the first to bake a cake for a child's first birthday, but it's probably the Germans who actually modernized this tradition in the 18th century and made it what we know today.

German cakes typically included candles, one for each year the person had lived plus one more for good luck that they would survive the next. The Germans were also the first to start making a wish when blowing out the candles.
