Creating a date range option

There is the possibility to set a time stamp (day/month/year) as embedded data in the survey flow, e.g.
Current day: CD=${date://CurrentDate/d}
Current month: CM=${date://CurrentDate/m}
Current year: ${date://CurrentDate/Y}

The time frame between 2 and 30 days can then be calculated and displayed, or used for validation.

No, it is a third party JS library. You can load it from JSDelivr. Do a search on the Qualtrics Community and you'll find some examples.

> (2) How would I write the code for 2 days from today's date for the minimum date
Just like in the example I linked to:
```
minDate: new Date().fp_incr(2)
```

Click on the cog to the left of the question and select "Add JavaScript"

@TomG I'm trying a version of this but wanting datetime pickr, mindate for 5 business days in the future. Here is the code I have so far:

Qualtrics.SurveyEngine.addOnReady(function()
{
/*Place your JavaScript here to run when the page is fully displayed*/
jQuery("#"+this.questionId+" .InputText").flatpickr();
})
{
enableTime: true
dateFormat: "Y-m-d H:i"
}
{
minDate: new Date().fp_incr(7)
}

This doesn't seem to do anything and I think it's because I've missed something in the code. Can you provide some support?

Thank you!

@TomG Thank you! Worked like a charm.

> Hi @TomG (or anyone really) but I'm still struggling trying to understand how to input the range needed. I am looking for due date of people's pregnancy which occurs in the future. For my date question, I want to make sure that individuals insert a date that is in the future from the day they participate in the survey (e.g. if today's date is 12.31.2019, they must input a date that is after 12.31.2019). From the flatpickr examples, they require a base minimum date which technically will change. Any insight would be helpful - thank you!

Just like the example above:
```
mindate: new Date().fp_incr(1)
```

Two things...

First, your flatpickr stylesheet link should be in the survey header along with the flatpickr JS (if you don't already have it).

Second, your jQuery selector is wrong. Your first example is the closest, but JS variables are case sensitive. It should be:
```
jQuery("#"+this.questionId+" .InputText")
```

> Hi @TomG - thank you so much for your help! I'm still unable to get it to work - I'm wondering if my source code is incorrect?
The stylesheet link should be in the survey header before the JavaScript, not the question text.

> Hi @TomG - is this where it should go (screenshot below)? I also tried to add it to the JS script for the question and got an error message (screenshot below). Thank you so much for your help!
Update the survey header under Look & Feel/General. Use source (<>) mode. This is the same place you should have placed the Flatpickr script link.
