AngularJS Datepicker displaying incorrect dates

Question

AngularJS Datepicker displaying incorrect dates

I have encountered an issue with the datepicker I am using (specifically AngularStrap's datepicker) where it seems to be consistently displaying a date that is one day behind due to how dates are calculated in javascript. My main concern is figuring out how to prevent the timezone from being taken into account and simply sticking with the date entered without any adjustments.

For example, when I select February 1, 2014 in the datepicker interface, the displayed value shows as 2/1/2014 but ends up being saved as

Fri Jan 31 2014 19:00:00 GMT-0500 (EST)

, as it subtracts the 5 hours for my timezone from the input date. This behavior is not what I want. I expect the selected date to be preserved as entered, regardless of timezones.

My question is, what would be the most effective approach to alter or manipulate this value so that entering 2/1/2014 results in exactly that date, without any timezone conversion? Should I consider modifying the code within the datepicker itself (though I feel this might not be ideal)? Or could the solution involve adjusting the value before sending it to the backend by incorporating some kind of offset? If so, how can I add time to a value that appears in the console as

Fri Jan 31 2014 19:00:00 GMT-0500 (EST)

?

I came up with a solution for this issue using a unique directive https://gist.github.com/davidsmith/ab439e0cd6b10c4a8f3c

While I initially designed it for Angular Bootstrap datepicker, I believe it should also function with AngularStrap datepicker since it relies on ngModel rather than the specific datepicker component.

The key aspect is that the value is reformatted every time a date is chosen on the datepicker (the formatted string yyyy-mm-dd is saved to the model), and when the model is accessed for display, it needs to be converted back to a Date object so the datepicker can handle it appropriately.

In essence, it performs the exact intercepts as mentioned in your query.

Although this thread may be old, since no solution has been accepted yet, I wanted to share what ultimately worked for me after a lot of trial and error:

In my situation, the issue lied in the datepicker using the incorrect timezone. This caused the wrong date to display when trying to edit an event, even though the correct date was saved in the database. The following code snippet resolved the issue for me:

 var evDate = new Date(data.eventDate); //data.eventDate is the date string
 evDate.setMinutes(evDate.getMinutes() + evDate.getTimezoneOffset()); 

 $scope.eventInfo.eventDate = evDate;

When it comes to handling dates in JavaScript, MomentJS is a great tool that can simplify the process without needing additional resources. By using `moment(datepicker value).local()`, you can easily obtain the date without worrying about timezone offsets.

I have come up with a solution: start by converting that date to a string. Here is the code snippet you can use.

 var SelectDate = $scope.GetFormattedDate(Date.parse($("#Date").datepicker("getDate")));            
     $scope.GetFormattedDate = function (CalDate) {
            var re = /-?\d+/;
            var WDate = CalDate.toString();
            var m = re.exec(WDate);
            var lastDate = new Date(parseInt(m[0]));
            var mm = lastDate.getMonth() + 1;
            var dd = lastDate.getDate();
            var yyyy = lastDate.getFullYear();
            var formattedDate = mm + '/' + dd + '/' + yyyy;

            return formattedDate;
        }

Now simply pass SelectDate to your controller, and voila! The problem has been successfully resolved :)

If you're encountering this issue, it may be because you're reactively inputting data into the Bootstrap datepicker. I faced a similar problem myself and found a solution that worked for me.

dateBegin === null ? dateBegin = null : dateBegin = new Date(formatDate(dateBegin,'yyyy-MM-dd','en'));

If the date is null, set its value to null before adding it to your Form Group and Form Group Control.

this.ugovorForm = new FormGroup({'dateBegin': new FormControl(dateBegin)})

Otherwise, format the date using the formatDate property provided by Angular. I struggled with this issue for quite some time, especially when loading dates from a database. Good luck!
