Month-long celebrations in May
Asian American & Pacific Islander (AAPI) Heritage Month
Asian immigrants first arrived in the U.S. in 1587, but did you know the first Japanese immigrants arrived in the United States in May 1843? They did! This is just one of the reasons we recognize the contributions of all people of Asian American or Pacific Islander ancestry during May.
Mental Health Awareness Month
May is also Mental Health Awareness Month — a time to fight stigma, provide support, educate the public and advocate for policies that support people with mental illness and their families. (Note: May 5 is National Silence the Shame Day, an opportunity to eliminate mental health stigma, minimize health disparities and lower suicide rates among vulnerable populations.) Here are ways you can support employee mental health.
Military Appreciation Month
Military Appreciation Month reminds us to thank our service members and their families for their work. Armed Forces Day is May 16. (Note: May 25 is Memorial Day, a day that is more than just the unofficial start to summer. Memorial Day honors the people who died while serving in the U.S. military.)
Older Americans Month
Older Americans Month is a time to acknowledge the contributions of past generations to our country and learn their stories. (Go here to learn how any age-diverse workforce can be a competitive advantage.)
Speech & Hearing Awareness Month
Each May, Speech & Hearing Awareness Month (sometimes called Better Hearing & Speech Month) provides an opportunity to raise awareness about communication disorders and how we can create more inclusive environments.

People gather worldwide to laugh together and raise awareness of the many health benefits of laughter.
May the Fourth Be With You Day
Also known as Star Wars Day, this holiday was inspired by the iconic phrase "May the Force be with you," which fans have playfully turned into "May the fourth be with you." It's a fun day for Star Wars enthusiasts to dress up as their favorite characters, host movie marathons, and greet each other with this famous line.

Cinco de Mayo
Often confused with Mexican Independence Day (in September), Cinco de Mayo celebrates Mexico’s 1862 victory over France during the Franco-Mexican War.

May 25
Memorial Day
See Military Appreciation Month above for details.
Hajj
Hajj, one of the largest religious gatherings, is a profound journey of faith and reflection, held annually in Makkah (modern day Saudi Arabia). For 5-6 days each year, millions of Muslims come together to honor the sacrifice of Prophet Abraham and demonstrate unity and devotion to God. The simplicity of the pilgrims' attire symbolizes purity and equality, reminding everyone of the shared humanity.
To observe this period, workplaces can offer supportive messages to colleagues participating in or reflecting on Hajj. You might also organize a brief educational session to learn about this important pillar of Islam. If you're greeting someone, a heartfelt "May your Hajj be blessed and your journey rewarding" goes a long way!
May 26
Day of 'Arafah
The Day of ‘Arafah is a deeply significant day for Muslims worldwide. It is marked by prayer and fasting for those not on pilgrimage. It's a day of forgiveness, reflection and seeking mercy from God, as it commemorates the standing of pilgrims on the plain of ‘Arafah during Hajj.
In the workplace, consider allowing Muslim employees a break for prayer or reflection. If you want to greet someone on this day, you can say, "May your Day of ‘Arafah be blessed with peace and reflection." It's also a great opportunity to encourage everyone to engage in acts of kindness and generosity.
May 27
Eid al-Adha*
Starting at sundown on May 26, Eid al-Adha is a Muslim festival in remembrance of the faith of the Prophet Ibrahim. Ibrahim was prepared to sacrifice his son, but Allah provided a lamb instead.
For someone observing Eid al-Adha, you can greet them with "Eid Mubarak," which means "Blessed Eid." A more specific greeting for this holiday would be "Eid al-Adha Mubarak," which directly acknowledges the occasion. Another thoughtful message could be, "May your Eid be filled with joy, blessings and peace." These greetings convey good wishes and respect for the significance of the celebration.
*Indicates a holiday that begins at sundown the day prior.
