What is a content calendar?

The tool matters less than the columns. A spreadsheet is enough. Each row is one piece of content, and each row answers the same questions so that gaps are easy to see.

Say you run a small bakery and can post four times a week. Pick two or three themes, such as behind the scenes, how-to and customer stories, and rotate them. Set aside one day a month for the batch work: write captions, shoot clips and decide the calls to action. Then fill in the next four weeks in a single sitting. Leave one slot a week empty for something that happens that week, like a sell-out or a local event.

Tip: Plan the reply side too. If a Reel asks people to comment GUIDE, decide in advance what the automatic answer says and which link follows, so the post and the DM flow match.

A calendar is the plan; scheduling is a separate step. Many scheduling apps publish for you through Meta’s APIs. Meta’s developer documentation on content publishing says an app can publish single images, videos, Reels and carousels to Instagram professional accounts. It also says accounts have a limit on API-published posts per 24 hours and that apps which let people schedule posts should enforce it. It names an endpoint for checking current usage, so check the live limit in the documentation rather than trusting a number from a blog.

The same page lists gaps: for example, it says shopping tags and filters are not supported when publishing this way, and that JPEG is the only image format. A scheduling tool you use may add its own rules, so test one post before you queue a month.
