If you're a start-up company and are still growing your follower count, it's best to set your posting schedule on the hours where most people use their phones. If you use Facebook and Instagram, the best times to post are before work-8 to 9 AM, and during lunch-1 to 3 PM. When it comes to the days in a week, you can reach a maximum number of post views on Instagram from Monday to Friday at 11 AM, Facebook from Tuesday to Friday during lunchtime, and Tiktok every morning from 8 to 11 except Mondays and Fridays.
