According to its creators International Men’s Day is a time for men to highlight discrimination against them in areas of health, family law, education, media or other areas and to project their positive contributions and achievements. During past years the method of commemorating International Men's Day included public seminars, classroom activities at schools, radio and television programs, peaceful displays and marches, debates, panel discussions, and art displays. The manner of observing this annual day is optional, and any appropriate forums can be used. Early pioneers of IMD reminded that the day is not intended to compete against International Woman's Day, but is for the purpose of highlighting men's experiences. Each year a different theme is highlighted.

Celebrate manhood and the wonderful positive and valuable contributions our men, young men, and boys make to our communities and to our societies
Promote and Support gender equality, encouraging men to address responsibly and positively the challenges facing them in society
Demonstrate strength of character and courage in meeting the challenges that men face in society and in contributing to building stronger and better communities, where people can be safe and grow to reach their full potential.[9]
According to Mens Activism News Network International Men's Day also interfaces with 'Movember' - a worldwide moustache growing charity event held during November each year that raises funds and awareness for men's health, one of the key themes promoted on IMD. It also interfaces with Universal Children's Day on Nov 20 and forms a 48 hour celebration firstly of men, then children respectively, with a recognition of the bonds between them.
