Social Media Calendar, 2025

It can be tough to come up with clever content for your social channels, 24/7, 365 days a year.

So we’ve put together a 2025 Social Media Holidays Calendar to help your content planning for the year.

Whether you’re looking for a way to celebrate the discovery of alien life (Science Fiction Day on January 2) or to highlight a nostalgic bygone piece of technology (National Landline Telephone Day on March 10), we’ve got you covered.

The calendar also includes a complete list of monthly celebrations such as Pride and Women's History Month.
