About the Kids Bedtime Calculator

The Kids Bedtime Calculator is a free tool that helps parents determine the right bedtime for children of any age, based on published sleep science from the American Academy of Sleep Medicine. Enter a wake-up time and your child's age to get recommended bedtimes and a full evening routine timeline.

Why we built this

We built this because the AAPs sleep guidelines are well-documented but not easy to apply quickly in everyday parenting. A simple calculator solves that in seconds.
