This could come in pretty handy!
Ah sleep... we love it but it can be a troubling one if you're not getting enough.
When you've a hectic schedule, or one that changes often, it can be really tough to get into a good sleeping pattern.
Well, lucky for us, Hillary's have come up with a quirky little solution: A Sleep Calculator.
Hillary's is an online retailer of made-to-measure blinds, shutters & curtains.
When you pop onto the online site @hillarys.co.uk, it's a really quick and easy process.
Basically you just put in the time you need to wake up, and it gives you multiple options of the perfect time for you to climb into bed.
It even takes into account the average time you need to fall asleep - which apparently is 14 minutes.
The Sleep Calculator works by counting in sleep cycles, each of which lasts around 90 minutes and you should pass through five or six of them each night.
On the site, they also have a sleep calculator specifically for kids along with one for parents who've missed out on sleep because of those kids!
We're definitely gonna test this out tonight and see if it helps!
