Mental Health Awareness Month: Dates, Color & How to Help

Mental Health Awareness Month is observed every May in the United States — and has been since 1949. Its symbol is the green awareness ribbon, and its goal is to reduce stigma, share resources, and rally communities around mental well-being.

For businesses, schools, and nonprofits, May is the anchor point of the mental-health calendar: the moment when employee-wellness programs, campus campaigns, and fundraisers reach the widest audience. This guide covers when Mental Health Awareness Month is, why the color is green, how it differs from World Mental Health Day on October 10, and practical, respectful ways your organization can take part.

When Is Mental Health Awareness Month? (May vs. October)

A lot of teams plan campaigns in the wrong month because two well-known observances sit on opposite sides of the calendar. Here's the distinction at a glance:

So if someone asks whether October or May is a "mental health month," the precise answer is that May is the U.S. awareness month, while October 10 is World Mental Health Day — a worldwide day of recognition. Both use green, and many organizations run touchpoints in both windows.

The Green Ribbon: Mental Health's Awareness Color

Green is the color tied to mental health awareness, and the green ribbon is its recognized symbol — a sign of hope, strength, and solidarity with those living with mental health conditions. Wearing or displaying green is a simple, visible way to signal that a workplace, campus, or community is a safe and supportive place to talk about mental health.

For a campaign, matching that official green is what makes it instantly readable. A few ways organizations put the green ribbon to work:

• Green silicone wristbands handed out at orientation, wellness fairs, or fundraisers.
• Green lapel pins worn by staff and volunteers so supporters are easy to spot.
• Green ribbons and apparel for walks, awareness weeks, and campus events.

If you're choosing a ribbon color for any cause, our awareness ribbon colors guide maps every color to its cause so you don't have to guess.

Mental Health Awareness Month: History & Theme

Mental Health Awareness Month has one of the longest histories of any U.S. observance. It was established in 1949 by Mental Health America (MHA), then known as the National Association for Mental Health, and has been observed every May since. Over more than seven decades it has grown from a small public-education effort into a nationwide moment that workplaces, schools, hospitals, and nonprofits build entire campaigns around.

Each year, leading organizations like MHA and NAMI publish an annual theme and toolkit to focus the conversation. Because Mental Health Awareness Month falls in May, the current year's official theme and materials are released by those organizations ahead of May — check Mental Health America and NAMI for the latest theme and free campaign resources rather than relying on last year's.

World Mental Health Day (October 10)

World Mental Health Day is October 10 every year — a global observance recognized by the World Health Organization (WHO). It exists so the conversation isn't limited to one country or one month: October 10 gives multinational companies, global nonprofits, and schools a worldwide moment to align messaging and activities.

Why does that matter for planning? Two reasons:

• Two campaign windows. May (U.S.) and October 10 (global) let you refresh a single mental-health initiative twice a year instead of once.
• Global teams. If your organization spans borders, October 10 is often the more inclusive date for company-wide participation.

Many organizations order green merchandise once and deploy it across both May and October 10, which keeps per-unit costs low while doubling the visibility.

Ways to Participate & Show Support

The strongest campaigns pair visible symbols (so people feel permission to talk) with real resources (so they know where to turn). Here are mental health awareness ideas organized by who's running the campaign:

For businesses & employers

• Add a green-ribbon week to your wellness calendar and share your Employee Assistance Program (EAP) details.
• Give staff green awareness wristbands or lapel pins to wear through May.
• Host a lunch-and-learn with a local mental-health nonprofit and post the 988 Suicide & Crisis Lifeline and other resources in break rooms.

For schools & universities

• Run a "Green Out" spirit day where students and staff wear green or custom t-shirts.
• Set up resource tables with counseling-center info and hand out branded wristbands.
• Tie the effort to campus walks or fundraisers in May.

For nonprofits & community groups

• Sell or distribute green ribbons, awareness wristbands, and lapel pins to fund programs — they're inexpensive in bulk and double as keepsakes.
• Organize a community walk and brand the gear with your event name and date.
• Partner with local businesses to co-sponsor merchandise and amplify reach.

Mental Health Awareness Products & Merchandise

Custom merchandise is where a mental-health campaign becomes self-sustaining: supporters wear it, talk about it, and — when you sell it — help fund the cause. Because awareness products are inexpensive at volume, they're well suited to walks, school campaigns, and corporate wellness initiatives — and you can order free samples to confirm the green matches before committing to a bulk run. Popular formats:

Add your organization's name, event date, or the green ribbon — following our artwork guidelines for a clean print — and a single bulk order covers both May and World Mental Health Day in October.
