The organizers of the strike called on women and non-binary individuals to stop paid and unpaid work for a full day, including childcare, housework, and "other family or household-related responsibilities."

Thousands of women gathered at Arnarholl, a hill in the capital city of Reykjavik, and dozens of other events took place across the country in places like Drangsnes, Hvammstangi, and Raufarhofn.

According to the organizers, women earn approximately 21% less than men in Iceland, and the gender pay gap is most pronounced among immigrant women, women in healthcare, and those with children, disabilities, or elderly dependents.

"This is the seventh time since 1975 that Icelandic women have gone on strike, though this marks the first 24-hour strike. In 1975, more than 90% of women participated in a strike, which paved the way for Vigdís Finnbogadóttir to become the world's first democratically elected female president," according to Iceland's Ministry of Foreign Affairs.

Other strikes occurred in 1985, 2005, 2010, 2016, and 2018, protesting the gender pay gap, sexual violence, and in support of the #MeToo movement.

"Their activism for equality has changed Icelandic society for the better and continues to do so today," said Iceland's President Guðni Jóhannesson.

Eliza Reid, a writer and the wife of President Jóhannesson, mentioned the 1975 strike in her out-of-office message on Tuesday.

"Nearly half a century later, equality is still a long way off, so this is a reminder," she said. "So, I won't be responding to emails today. You can expect my reply tomorrow when I return to work."

The strike was organized by groups such as the Icelandic Feminist Initiative, "Women in Film and Technology," and the international society "Delta Kappa Gamma."

Men were encouraged to step in for women and non-binary individuals at work and at home in their absence.

"Those who can should rely on fathers or other male relatives to take care of the child/children on this day," the organizers stated. "Not every child has a father, and of course, not all fathers are present. Unless otherwise stated, children, girls, and boys are welcome at the demonstration[s] and gatherings."
