Unions, feminist associations and left-wing parties have called for a work stoppage for two hours on March 8, hoping to recreate the strike and mass protests seen nationwide to mark the same day in 2018.
But things are different this year.
Political parties are already busy campaigning for upcoming snap general elections on April 28 and European, regional and municipal polls on May 26th.
The ruling Socialist party, centre-right Ciudadanos and the conservative Popular Party (PP) have all raced to pledge to do their bit against gender inequality in a country with a strong feminist movement.
But virulent anti-feminism rhetoric has also made its entrance, with far-right party Vox and an ultra-conservative association that chartered a bus with the slogan “#StopFeminazis” coupled with a picture of Hitler wearing pink lipstick.

Feminism — defined as the advocacy of women's rights on the ground of the equality of the sexes — like poverty or wealth redistribution, are usually more the remit of the left, says Cristina Monge, sociology professor at the University of Zaragoza.
Socialist Prime Minister Pedro Sanchez has made them a central theme of his campaign.
On Friday in its cabinet meeting, the socialist government — which has the most female ministers in Spain's history — approved a number of progressive measures.
Among them, a gradual increase in paternity leave so that it equals maternity leave by 2021, and more transparency on salaries in companies.
They aim to reduce the gender pay gap, which stood at 14.2 percent in Spain and 16.2 percent in the European Union in 2016, according to the latest Eurostat figures.
But Spain's right-wing parties have also embraced feminism for years, even if they have not called to mobilise on March 8th.
Centre-right party Ciudadanos on Sunday unveiled a manifesto for “liberal feminism” that defends gender equality and “doesn't exclude men.”
Conservative PP meanwhile has glossed over a speech by its leader Pablo Casado criticising abortion and is pledging to reduce the gender pay gap and help women enter the labour market.
“Let's not let them speak in our name,” said outgoing parliament speaker Ana Pastor in a PP campaign video — in reference to the left.
“That's tangible proof that feminism is here to stay and sells” politically, Professor Monge said. “Many right-wing people… won't tolerate that their party oppose it.”
In Spain, 77 percent say a strike on March 8th is justified, according to a survey by polling firm Metroscopia published Monday.
That, however, is five percentage points less than a year ago, particularly among those on the right as Vox's popularity increases.
The far-right party, which could play a decisive role after elections in helping other right-wing parties secure a majority in parliament, opposes a law against gender violence that it feels is “ideological” and “discriminatory” towards men.
The bus chartered by conservative, Catholic association HazteOir (“Make yourself heard”), which compares feminists to Nazis, has been driving around the country for several days.
It is protesting against a law fighting gender violence, another for gender equality and yet more for LGBT rights, arguing these all discriminate against men.
Prosecutors in Barcelona asked the bus to be stopped when it came to the Mediterranean city, charging it incites hate and discrimination, but a judge refused to do so, citing freedom of expression.
Meanwhile the “Women of the World Global Platform,” a Spanish initiative that groups together conservative associations from around the world, has called for a counter-protest in central Madrid on March 10.
International Women's Day “has converted into a day for those who reject femininity as well as masculinity, complementarity, maternity and dedication to the family,” spokeswoman Leonor Tamayo said in a statement.
“But we want to celebrate it, confirm it and reclaim it.”
