Is there really a best time of day to post on Instagram so that your photos and videos get more views, likes, and comments? Figuring this out can be a little tricky.

First, because Instagram is primarily accessed on a mobile device, users can quickly glance at their Instagram feed at any time and from almost anywhere. Posting, viewing, and interaction habits on Instagram tend to be very different than on other social networks, making it a little harder to determine when users are most active.

Oh, and there's another big thing that Instagram recently introduced.

Remember when Instagram posts were shown in chronological order? That's definitely not the case anymore.
