Answer 1

The old answers to this question are ok...

However, the official documentation suggests a new, more concise solution:

First set the day you want to be the lower bound

 var today = new Date().toISOString().slice(0,10);

Then include the range using validRange. Simply omit the end date.

 validRange: {
    start: today
 }
