For more than 100 years, March 8th has marked what has come to be known as International Women's Day in countries around the world. While its purpose differs from place to place—in some countries it's a day of protest, in others it's a way to celebrate the accomplishments of women and promote gender equality—the holiday is more than just a simple hashtag. Ahead of this year's celebration, let's take a moment to explore the day’s origins and traditions.

1. International Women's Day originated more than 100 years ago.

On February 28, 1909, the now-dissolved Socialist Party of America organized the first National Woman's Day, which took place on the last Sunday in February. In 1910, Clara Zetkin—the leader of Germany’s 'Women's Office' for the Social Democratic Party—proposed the idea of a global International Women's Day, so that people around the world could celebrate at the same time. On March 19, 1911, the first International Women's Day was held; more than 1 million people in Germany, Switzerland, Austria, and Denmark took part.

2. The celebration got women the vote in Russia.

In 1917, women in Russia honored the day by beginning a strike for "bread and peace" as a way to protest World War I and advocate for gender parity. Czar Nicholas II, the country's leader at the time, was not impressed and instructed General Khabalov of the Petrograd Military District to put an end to the protests—and to shoot any woman who refused to stand down. But the women wouldn't be intimidated and continued their protests, which led the Czar to abdicate just days later. The provisional government then granted women in Russia the right to vote.

3. The United Nations officially adopted International Women's Day in 1975.

In 1975, the United Nations—which had dubbed the year International Women's Year—celebrated International Women's Day on March 8th for the first time. Since then, the UN has become the primary sponsor of the annual event and has encouraged even more countries around the world to embrace the holiday and its goal of celebrating "acts of courage and determination by ordinary women who have played an extraordinary role in the history of their countries and communities."

4. International Women's Day is an official holiday in dozens of countries.

International Women's Day is a day of celebration around the world, and an official holiday in dozens of countries. Afghanistan, Cuba, Vietnam, Uganda, Mongolia, Georgia, Laos, Cambodia, Armenia, Belarus, Montenegro, Russia, and Ukraine are just some of the places where March 8th is recognized as an official holiday.

5. International Women's Day is a combined celebration with Mother's Day in several places.

In the same way that Mother's Day doubles as a sort of women's appreciation day, the two holidays are combined in some countries, including Serbia, Albania, Macedonia, and Uzbekistan. On this day, children present their mothers and grandmothers with small gifts and tokens of love and appreciation.

6. Each year's International Women's Day festivities have an official theme.

In 1996, the UN created a theme for that year's International Women's Day: Celebrating the Past, Planning for the Future. In 1997, it was "Women at the Peace Table," then "Women and Human Rights" in 1998. They've continued this themed tradition in the years since; for 2020, it's "Let's all be each for equal" or #EachforEqual.

A Rare Blue Moon Will Light Up the Night Sky This Halloween

Wolves, werewolves, and people dressed as werewolves will have a bona fide full moon to howl at this Halloween. And it’s not just any full moon—it’s a blue moon.

What Is a Blue Moon?

Since a complete lunar cycle is 29.5 days long, this usually works out to one full moon per calendar month. If a full moon occurs on the first or second day of the month, however, there could technically be another one within the same month. When that happens—about once every 2.5 to 3 years, according to the Farmers’ Almanac—the second full moon is called a “blue moon.”

But up until the mid-20th century, blue moons had a different definition. The Maine Farmers’ Almanac and similar publications used to count full moons by season, so a year with 13 full moons meant that one season would have four (not three) full moons. To avoid messing with full moon nicknames that were tied to certain times of year (e.g. the “moon before Yule”), the third full moon in a season of four was named a “blue moon.”

In a 1943 column for Sky & Telescope, Laurence J. Lafleur mentioned that blue moons occur when a year has 13 full moons, but he didn’t go into detail about how the Maine Farmers’ Almanac determined which moon was, in fact, the blue one. Three years later, another Sky & Telescope author, James Hugh Pruett, wrote an article in which he incorrectly assumed that the blue moon was the second full moon in a month with two. The magazine repeated Pruett’s rule in future stories, and it eventually caught on with the general public.

Why Is It Called a “Blue Moon”?

Just like a pink moon isn’t pink and a worm moon isn’t crawling with worms, a blue moon isn’t actually blue. One theory holds that the name is derived from the Old English word belewe, or “to betray”—perhaps since blue moons betray the normal schedule of full moons. This lunar rarity is also said to be the origin of the phrase once in a blue moon.

The moon actually has appeared blue in the past. After a massive volcanic eruption, the ash in the sky can sometimes block red light particles, giving the moon a bluish tint. According to NASA, this happened after Indonesia’s Krakatoa erupted in 1883, and again when Mexico’s El Chichón spewed its molten guts a century later.

When Can I See October’s Blue Moon?

October's first full moon, the harvest moon, is coming on Thursday, October 1. The second one, the blue moon, will peak on Saturday, October 31, at 10:49 a.m. EST, so you’ll be able to see it before the sun rises or after it sets. Since a full moon on Halloween only happens once every 19 years or so, cross your fingers for clear skies that night.
