Javascript Date Plus 2 Weeks (14 days)

Question

I use this to get the date:

var currentTime = new Date()
var month = currentTime.getMonth() + 1
var day = currentTime.getDate()
var year = currentTime.getFu         


        

Answer 1

12096e5 is a kind of magic number. Just 14 days in milliseconds in exponential notation.

This number is the result of 1000[ms] * 60[s] * 60[m] * 24[h] * 14[d] saved in exponential notation.

You can check it if you type Number('12096e5'). You will get 1209600000 [ms] which is exactly 2 weeks in milliseconds. The exponential notation makes it obscure.

You can write any other number in exponential notation to make the life of your fellow developers more interesting.

Date object has constructor which accepts milliseconds as an argument which argument can be in exponential notation.

var d = new Date(milliseconds);

var afterTwoWeeks = new Date(+new Date + 12096e5);
var afterTwoWeeks = new Date(+new Date + 1209600000);

Both are the same.
