I am trying this but is not working... why?
<html> <body> <script type="text/javascript"> var today=new Date(); //today is Nov 28, 2010 today.setHours(0); today.setMinutes(0); today.setSeconds(0); document.write(today+" "); var today2 = new Date("November 28, 2010"); document.write(today2 + " "); if (today == today2) { document.write("=="); if (!(today > today2) && !(today < today2) ) {document.write("== ");} if (today > today2) { document.write("> ");} if (today >= today2 ){ document.write(">= ");} if (today < today2 ) { document.write("< ");} if (today <= today2 ){ document.write("<= ");} </script> </body> </html> And I always get this:
Sun Nov 28 2010 00:00:00 GMT+0900 (JST) Sun Nov 28 2010 00:00:00 GMT+0900 (JST) > >= Aren't both dates to be the same? Hence, I should get == printed but is not happening... ;(
Thank you for your help in advance.

To check if a date is today's date:Use the toDateString() method to compare the two dates. If the method returns 2 equal strings, the date is today's date.
Use new Date() to generate a new Date object containing the current date and time. This will give you today's date in the format of mm/dd/yyyy. Simply change today = mm +'/'+ dd +'/'+ yyyy; to whatever format you wish.
To check if two dates are the same day, call the toDateString() method on both Date() objects and compare the results. If the output from calling the method is the same, the dates are the same day.
They will never match because you're comparing two separate Date object instances.
You need to get some common value that can be compared. For example .toDateString().
today.toDateString() == today2.toDateString(); // true If you just compare two separate Date objects, even if they have the exact same date value, they are still different.
For example:
today == new Date( today ); // false They are the same date/time value, but are not the same object, so the result is false.

function today(td) { var d = new Date(); return td.getDate() == d.getDate() && td.getMonth() == d.getMonth() && td.getFullYear() == d.getFullYear(); } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
