First EU equal pay day on 5 March signals a commitment to end discrimination against women at work.
Equal pay for equal work relates to one of the EU's founding principles, non-discrimination. While the pay gap between men and women doing the same job has fallen, progress has been too slow - women still earn 17.5% less on average than men.
Equal pay day is on 5 March for a specific reason. To match the amount a man earns in one year, a woman - earning 17.5% less - would have to work an extra two months - until 5 March.
The pay gap amounts to ongoing discrimination and inequality in the workplace and has far-reaching effects. For example, less pay means a lower pension. As a result, 22% of women aged 65 and over are at risk of poverty compared to 16% of men.

The EU also works to end another workplace discrimination - the gender barrier preventing women from advancing into top jobs.
Following a meeting with business leaders this week, the Commission launched a voluntary way for public companies to pledge they will raise the number of women on their boards to 30% by 2015 and to 40% by 2050.
After a year, the EU will assess progress. If it is unsatisfactory, the Commission will look at steps - including a law - to force change at the top. Currently, only 12% of board members of Europe's largest companies are women.
The approaches to end discrimination follow the Commission's gender equality strategy and will also be highlighted on International Women's Day on 8 March.
