For days, months - even years - the girl development community has worked to put girls on the agenda. To make them a priority. To make the world understand that girls are the most powerful force for change on the planet.
And now it's happening.
Today, on the second annual International Day of the Girl (IDG), girls from Egypt, Burkina Faso and Nepal will descend upon the United Nations to command the attention of global leaders in a ceremonial handover of the Girl Declaration.
Thanks to the unwavering effort (and loud voices) of the Girl Effect community - the words of the Girl Declaration will be heard by receptive ears.
Earlier this week, the UN secretary-general, Ban Ki-moon, publicly backed the Girl Declaration, saying: "To achieve meaningful results, we need fresh solutions to girls' education challenges and we must heed the voices of young people."
"I have heard from girls around the world participating in the consultations for the new Girl Declaration. I resolve to ensure that Global Education First mobilises all partners to respond to their powerful call for empowerment."
Global leaders unite
Since its launch on 1 October, more than 30,000 people have read and shared the Declaration, a call to action to embed girls' interests in the post-2015 development goals.
Created by 25 development organisations in conjunction with 508 girls in 14 countries, the Declaration has already been signed and endorsed by the likes of Oprah Winfrey, Archbishop Desmond Tutu, Queen Rania of Jordan, Malala Yousafzai, Richard Branson, Barbara Bush and Gordon Brown.
In urging her own networks to get involved, Oprah said yesterday: "We are enough. We matter. We are NOT invisible. Girls around the world are having their say. This is the moment to listen."
Leaders in government, business and public organisations have also added their names in support, including the World Bank, USAid, Nike, Intel, Microsoft, Johnson & Johnson, Unilever and the United Nations Foundation.
