What would be the best way to compare two dates?

var int = e.parameter.intlistbox;
var startDate = rSheet.getRange(parseInt(int) + 1 ,1).getValues();
// returns Sat Jun 30 2012 00:00:00 GMT-0300 (BRT) 
var toDay = new Date();
// Sat Jun 23 2012 22:24:56 GMT-0300 (BRT)

if (startDate > toDay){ ....

I saw the .toString() option but that seems to work only for == or === operator.

Anything clear about this matter?


The Date object has the valueOf method which returns the number of milliseconds since midnight 1970-01-01. You can use it to compare dates. Something like

var date01 = new Date();
var date02 = new Date(2012, 5, 24);
if (date01.valueOf() > date02.valueOf()) {
   ....
}

Compare two dates Google apps script - date - iOS, What would be the best way to compare two dates? var int = e.parameter. intlistbox; var startDate = rSheet.getRange(parseInt(int) + 1 ,1).getValues(); // returns� les objets Date peuvent être comparés comme n'importe quelle autre variable. La seule chose délicate est si vous avez besoin de comparer deux dates sur le même jour par exemple et s'attendre à obtenir date A = date B , dans ce cas, vous avez un problème puisque les dates comprennent également des heures et des minutes (et deuxième + millisecondes) !


Wow, I'm late here. I found it easiest to convert the dates into the integer Day of the year. So Jan 1st would be 1, Feb 1st would be 32, etc.

Here is that script:

today = parseInt(Utilities.formatDate(new Date(),"EST","D"));

If you're grabbing a value from your spreadsheet, just place the value into the new Date():

today = parseInt(Utilities.formatDate(new Date(rSheet.getRange(parseInt(int) + 1 ,1).getValues()),"EST","D"));

The DATEDIF is not part of Google Sheets Query. The dateDiff() function in Query (see the double “F”) finds the date difference between two dates. But the DATEDIF is far more advanced. You can use the DATEDIF function to calculate the number of days, months, or years between two dates.


Date objects can be compared just as any other variables. The only tricky thing is if you need to compare two dates on the same day for example and expect to get date A = date B , in this case you have a problem since dates also include hours and minutes (and second + milliseconds) ! (that's why I suggested to use strings to check equality in the post you refer to). What you could do is to set hours, minutes, seconds and milliseconds to 0 in both variables so the comparison occurs on day, month, year only. See w3schools date reference page to see how to do that.

Another possibility would be to convert both dates to strings using Utilities.formatDate() and play with substrings() to get the data you need but I guess this is not a very elegant way to proceed ;-)

To check whether the timezones agree, you can either compare both manually, or do something like this: var sheet = SpreadsheetApp.getActiveSheet (); sheet.getRange ('A1').setFormula ('=date (2015,1,1)'); Logger.log (sheet.getRange ('A1').getValue ().getHours ()); This inputs the formula =date (2015,1,1) in the cell A1.
