Can’t quite get bedtimes down? Always waking up too early or too late? Never fear, the internet is here to help. Start Sleeping is the web sleep calculator that will work out when you should be going to bed or getting up to get the most out of dream time.

The calculator is really easy to use. Just input your age, tell it when you want to wake up or when you want to go to bed and it will spit out a few recommended times for you to build your routine around. Simple, quick and if you’re struggling with sleep, worth a try.

The site also has a good deal of resources in the way of articles and posts to help you understand sleep and sleep health better so if that interests you, check out the added materials for some, perhaps, bedtime reading. Just remember to turn on your blue light filter. The site is free to use.
