If you want to put a birthday countdown on Instagram, there are a few things you need to do. First, open up the Instagram app and sign in. Next, go to your profile and click on the gear icon in the top right corner. From here, click on “Settings” and then “Birthdays.” Next, you will need to choose which days of the month your birthday is on. If it’s a weekend or holiday, Instagram will automatically choose one of those days for you. If it’s not one of those days, you will need to choose which day of the week your birthday is on. Finally, enter in the date of your birthday and hit “Save Changes.” Now that everything is set up, all you have to do is start counting down! To start off, post a picture or video that features yourself or someone special celebrating your birthday. Then follow these simple tips for keeping your countdown interesting: -Post new pictures or videos every day until your birthday arrives; this will keep everyone excited about what’s coming next! -Share funny stories about how old you feel today (or any other funny memories from your birthdays past) -Give away freebies (like cake recipes or party supplies) as part of your celebration -Make a wish for everyone who follows your countdown (or yourself!) ..
