Instagram is great for sharing tons of photos with your friends when you’re out and about, but some people will use almost any excuse to post photos and connect with other users. Trendy Instagram hashtags that are meant to be used on specific days of the week, like Thursday, Friday, Saturday, Sunday, and the rest of the week, are a great way to do just that.

Hashtags that relate to a specific day of the week usually have a certain theme, which is why they are so popular these days. For example, #ThrowbackThursday (or #TBT) encourages Instagram users to post an old photo on Thursday.

Throwback Thursday may be the weekday hashtag trend most embraced by social media enthusiasts around the world, but if you need an excuse to post on Monday, Saturday, or whenever, you’re going to have to find a different hashtag to use. There are endless weekday hashtag trends for every day of the week, and they just keep growing.

Here are some great weekday hashtags that you can use right away. Simply pick a day of the week, find a photo with that theme, post it with the hashtag, and you're good to go!
