Sorry this has failed checks. I will revise and update

Checks passed! Let me know if you need anything else here.

Additionally, I wanted to note that I found a separate bug in both the master and my pr. The bug is that when minDate is set, the selectable days in the DateInput Calendar start one day before the minDate. The expected behavior is that the selectable days would start on the minDate. Since it's happening in the master and is not directly related to my pr or this issue, I did not fix it here. I will create a new issue shortly to address it.

I'd prefer this logic to be a little different to avoid accidental breaking changes. It should check whether the minDate is after the current date and only if it is, use it as the default date.

Good call. Code has been update. Let me know if any further tweaks are needed. Thanks
