This guide will help you plan ahead, tap into relevant moments, and craft campaigns that truly resonate.

1 May – Labour Day (Europe & International Workers’ Day – Worldwide)

A public holiday in many European countries, Labour Day (or International Workers’ Day) is a time to celebrate workers’ rights and achievements. Brands can use this opportunity to champion workplace culture, employee appreciation, or even promote work-life balance initiatives.

Content Tip: Share behind-the-scenes stories of your team, offer special discounts to customers who work in key industries, or highlight your company's fair labour practices.

4 May – Star Wars Day (Worldwide)

A fan-driven celebration of the legendary sci-fi franchise, this day is a perfect excuse for brands to jump on pop culture trends.

Content Tip: Create fun, themed content with a ‘May the Fourth Be With You’ spin, offer limited-time promotions, or run a Star Wars-themed contest.

5 May – Early May Bank Holiday (UK)

A significant shopping and leisure weekend in the UK, this is a prime time for businesses to promote travel, retail, and lifestyle campaigns.

Content Tip: Run exclusive bank holiday sales, encourage staycation ideas, or promote outdoor activities and events.

9 May – Europe Day (European Union)

Celebrating peace and unity across Europe, this is a great time for brands operating in the EU to highlight their European connections, values, and collaborations.

12 May – International Nurses Day (Worldwide)

A day to appreciate healthcare professionals, particularly nurses, who play a vital role in society.
