Dear Fooloomanzoo,

Thank you so much for contributing these great packages to the community!
I was wondering if you could add the License file for property-mixins folder as well.

Sincerely,

if datetime var on that line is null(wich in javascript is also an object typeof null == "object"), this throws an error because getData on the if statement dont exists on null

will summit pr with fix soon

In the datetime-mixin there is something like:

          ...
           if (isNaN(d)) {
            d = new Date();
          }
          d.setMilliseconds(milliseconds || 0);
          d.setSeconds(seconds || 0);
          d.setMinutes(minutes || 0);
          d.setHours(hours || 0);
          if (day !== undefined) {
            d.setDate(day);
          }
          if (month !== undefined) {
            d.setMonth(month - 1);
          }
          ...

Above calculations are not working as expected under iOS Chrome version 63.0.3239.132, eg:

If I want to set 2018-01-29 and today is 2018-02-05
first the date is initialized with new Date() to current date. After that the day part is updated to be equal 29 but due to Date nature d object is actually set to be 2018-03-01, and in the end the month part is set. The final value of d is equal 2018-01-01.

The fast fix is to change the order d.setMonth() and than d.setDay().
