Here’s a look ahead at the month of October 2026 and some of the events, anniversaries and occasions that smart marketers can use as the basis for an event-driven promotion…
…to create your own marketing calendar for October 2026.
The most prominent occasion, beloved by many marketers, is “Halloween” on October 31. Given what’s already happened in 2026…
…Halloween might well provide some light relief!
The origins of Halloween seem to be a mixture of pagan festivals marking the end of summer…
…combined with the idea that at this time of the year the spirit-world comes close to our world…
…adopted by the Christian religion as the eve of “All Souls Day”.
Whatever, it’s the traditional occasion to acknowledge the afterlife and the supernatural.
So, an opportunity to use themes in your promotions like…
“It’s Scary What You Are Missing!”
“Now a spooktacular, very limited time, opportunity”
“Terrifyingly scary profits coming your way…”
…and so on.
The theme of FEAR (of loss, for example) can also be used…
…but don’t get too frightening about it!
