Irish women are "working for free" for the rest of the year, according to Dress for Success Dublin (DfSD), the charity behind the #WorkEqual campaign.
According to DfSD, today marks the date that women effectively stop earning, relative to men, because of the gender pay gap.
"We have a gender pay gap in Ireland of 13.9%. If you shave 13.9% off the end of the year, you land on today's date," Sonya Lennon, founder of DfSD, said.
She said today - Equal Pay Day - is a symbolic day to highlight the still existing pay gap between women and men.
Ms Lennon said that while progress was being made, change was happening slowly and more needed to be done to challenge societal and political attitudes.
"Lack of affordable childcare, gender stereotyping, inflexible work options and poor take-up of parental leave are all feeding into the persistent inequalities between women and men," Ms Lennon said.
The European Institute for Gender Equality (EIGE) publishes a Gender Equality Index to measure the progress of gender equality in all EU member states of the EU.
Ireland scored 71.3 out of 100 points in the 2019 index, which puts it above the EU average.
The index shows that women's mean monthly earnings are €2,808 in Ireland, compared to €3,423 for men, while the full-time equivalent employment rate for women is 43.9% compared to 60% for men.
The index also reveals that a woman's working life in Ireland lasts for 33.1 years - on average - compared to 40.1 for men.
It found 88.7% of women cook and/or do housework every day, compared with just 48% of men.
