All they really want is to give peace a chance.
The day — commonly referred to as "Peace Day" — is recognized by the United Nations as a day of global ceasefire and non-violence.
In the past, countries around the world have held concerts, sporting, education and different peace-fused events to mark the occasion.
Gilley has campaigned fervently for more than a decade in hopes of “institutionalizing” and spreading awareness of “Peace Day.”
“When people are made aware the day exists, they can make a difference in their own homes, schools and communities. They feel empowered that they are contributing to peace building, which is crucial given most of the violence that happens today occurs in our homes, schools and communities, ” Gilley told the Daily News.

The theme of this year's International Day of Peace promotes togetherness and unity: "Partnerships for Peace - Dignity for All."
Various organizations have taken to social media to promote how they will be celebrating this year's "Peace Day" and by challenging others to start up their own events, no matter how futile they may seem.
In honor of the International Day of Peace, here is a look at only some of the most famous and controversial advocates for peace throughout history, in no particular order:
1. Mother Teresa
Mother Teresa, recipient of the 1979 Nobel Peace Prize, would dedicate her life to caring for the sick and poor.
A woman who in life and death was not without her critics, Mother Teresa founded the Missionaries of Charity in Calcutta, India (now Kolkata), a religious order of women who ran hospices and homes for anyone in distress, including the terminally ill, blind, AIDS patients, lepers, the homeless, etc.
2. Mahatma Gandhi
Known for his ideas of nonviolent civil disobedience, Gandhi led the Indian people through the Salt March and the country’s quest to gain independence from British rule.
Gandhi was jailed several times during his efforts for peace and he often went on hunger strikes to protest the maltreatment of India’s poorest.
He was assassinated by a Hindu nationalist in 1948.
