International Women’s Day is today.  From the website:

Women’s organisations and governments around the world have also observed IWD annually on 8 March by holding large-scale events that honour women’s advancement and while diligently reminding of the continued vigilance and action required to ensure that women’s equality is gained and maintained in all aspects of life.  (from www.internationalwomensday.com)

In many countries, men honor mothers, wives, girlfriends, colleagues, and so forth with flowers and small gifts.  Others recognize it with events and activism.
