Date Format From JSON

I am using the date picker field for dates but noticed that on my JSON that gets generated is in a different format, what format is that in? Also is there a popular custom function to convert it back to the date?

This doesn’t look like the standard datepicker that’s built into BetterForms. Which library are you using, or can you post your JSON schema used to build that field?

“inputType”: “date”,
“label”: “Date of Birth”,
“model”: “clientDOB”,
“placeholder”: “”,
“required”: true,
“styleClasses”: “col-md-3”,
“type”: “input”

I believe it is the standard FM BetterForms date.

Try looking in the snippets for the date picker. That element has a key for “format” where you can specify how to format the date as a string when placed in your JSON. Then, FileMaker will read it easily

I just added a field to capture date as well, the format is “dateTimePickerOptions”: {
“format”: “YYYY-DD-MM”,
This is from the sample page.

the value I get back is: 1596168000000 for July 31, 2020

First I thought this was the FileMaker date as number representation, it is not as July 31,2020 is 737637. Where can I find the translation for this value?

Update: the string 1596168000000 looks like the millisecond representation of the timestamp based on UTC time.

Is there a simple date picker that works as a date? I’ll check the other examples out, maybe I picked the wrong one.

This is the JSON that worked for me:

            "dateTimePickerOptions": {
                "format": "MMM D, YYYY",
                "icons": {
                    "today": "fa fa-star"
                "showTodayButton": true
            "format": "MM/DD/YYYY",
            "label": "Date Of Birth",
            "model": "clientDOB",
            "required": true,
            "styleClasses": "col-md-3",
            "type": "dateTimePicker"

For future devs:
There are two format keys, they both use NumeralJS and format the displayed date and format the data date that is entered into the model.

I ended up using the date snippet and it gives only the date as expected.
