Menstrual hygiene day (MHD or MH Day ) is an annual awareness day , on 28 May, that aims to break taboos and raise awareness about the importance of good menstrual hygiene management (MHM) for women and adolescent girls worldwide. It was initiated by the German-based NGO
WASH United in 2014. The initiative for Menstrual Hygiene Day has received the support of over 270 global partners who are committed to making good menstrual health and hygiene a priority worldwide.
The day complements other important days of the year in relationship to sanitation and hygiene , such as 15 October for
Global Handwashing Day or 19 November for World Toilet Day. May 28 was chosen for its symbolism since May is the 5th month of the year and most women average 5 days every month and their cycle is approximately 28 days.
