In the notebook:

> I am very excited🕺 about the prospect of using Plot as the go-to tool for interactive data exploration😀. As I am trying to grasp the concept and the mental model behind the Plot API, I am browsing through the observable plot collection going through...

At the bottom, I have a function drawCalendar() which returns a Plot drawing the calendar.  
in Chrome the result is displayed as expected.

But when I open the page on an Iphone with the Safari browser, this cell:

drawCalendar(new Date(“3-8-2022”), new Date(“4-13-2022”))

is not displaying anything.

Any ideas?

Safari is stricter than Chrome on date parsing, and new Date(“3-8-2022”) returns an Invalid Date.

Thanks, I just recall I tripped over it before…

The following Date format seems to works across all browsers:

// “mm/dd/yyyy”  
new Date(“10/26/2020”);

If you’re going to use the Date constructor to parse dates, I recommend using ISO 8601 YYYY-MM-DD, such as `new Date("2022-03-08")`.
