Have you ever noticed how Google Calendar sometimes shows certain events in a larger, more eye-catching format, with a special graphic attached? It’s something you see when you click or tap to view an event both on the Calendar website and in the Calendar Android app and iOS app, too, and it happens automatically — without any effort whatsoever.

Those illustrations are triggered by the presence of special codewords within your event titles. And once you know what codewords cause which illustrations to appear, you can hack the system, in a sense, and make any event in your agenda stand out with a specific illustration around it.

Some of the codewords are pretty obvious, like the word “dentist” in an event’s title causing a graphic with toothbrushes to pop up, the word “haircut” in an event’s title generating a graphic with a blowdryer and scissors, or the word “Thanksgiving” in an event’s title generating — well, y’know.

But others are terms you’d probably never think to use in your agenda — not deliberately, anyway.

Below, for the first time, is the complete and typically unpublished list of secret Google Calendar codewords (now updated to include a bunch of more recent additions!). Check ’em out, try some out, and find the ones you like — then custom code your calendar and make your important events stand out with the flair they deserve.
