Javascript if time is between 7pm and 7am do this?
var today = new Date().getHours();if (today >= 7 && today <= 19) { document.body.style.background = "Red";} else { document.body.style.background = "Blue";}See fiddle.
I suggest using a class on the body to manage the style, but handle the classes in JavaScript.
Essentially you'll use the Date class to get the current hour in military time (24 hour). 7 PM is represented as 19 in military time.
var hour = new Date().getHours();// between 7 PM and 7 AM respectivelyif(hour >= 19 || hour <= 7) { document.body.className += 'between7';} else { document.body.className += 'notBetween7';}Then in CSS you can handle those classes.
body.between7 { background-color: green;}body.notBetween7 { background-color: red;}
Here is JSBin
var currentTime = new Date().getHours();if (currentTime >= 19 && currentTime <= 7) { document.body.style.background = "/*your X color*/";} else { document.body.style.background = "/*your Y color*/";}
