Question

I would like to have array in numbering for days and months from starting day 1 or month 1 till todate.

For example:
Today is 05-Oct-2012

Array for days: Output (1,2,3,4,5)

Array for months: Output (1,2,3,4,5,6,7,8,9,10)

Those array will be use in axis-x for charts.

Answer 1

You can use the Date object together with this useful Array.range() implementation to get the arrays;

var date = new Date("05-Oct-2012");
var days = Array.range(1, date.getDate());
console.log(days);
var months = Array.range(1, date.getMonth() + 1);  // Zero-based, so add one.
console.log(months);
