how to check a date is within current week or current month or next month in javascript?

I have some friends' birthdays and want to separate them as follows :

birthdays which fall within the current week (within remaining days of current week starting from current day).

birthdays which fall within the current month (within remaining days of current month starting from current day).

birthdays which fall within the next month.

So all I want to know how to test each date in javascript to see if it falls within the remaining days of the current week/current month/next month.

N.B: say I have those dates in m/d/Y(06/29/1990) format.

Thanks

Convert your date and current time to Date object and use it for comparison. Some dry coding:

var now = new Date()

if (

   (check.getFullYear() == now.getFullYear()) &&

   (check.getMonth() == now.getMonth()) &&

   (check.getDate() >= now.getDate())

) {

   // remanining days in current month and today. Use > if you don't need today.

}



var nextMonth = now.getMonth() + 1

var nextYear = now.getFullYear()

if (nextMonth == 12) {

   nextMonth = 0

   nextYear++

}

if (

   (check.getFullYear() == nextYear) &&

   (check.getMonth() == nextMonth)

) {

   // any day in next month. Doesn't include current month remaining days.

}



var now = new Date()

now.setHours(12)

now.setMinutes(0)

now.setSeconds(0)

now.setMilliseconds(0)

var end_of_week = new Date(now.getTime() + (6 - now.getDay()) * 24*60*60*1000 )

end_of_week.setHours(23)

end_of_week.setMinutes(59)

end_of_week.setSeconds(59) // gee, bye-bye leap second

if ( check >=now && check <= end_of_week) {

   // between now and end of week

}
