disabled times isInvalidTime function?

[kevinjavitz]

Is there any way to disable times like there is with dates? similar to isInvalidDate but an isInvalidTime? Or has someone forked and added this feature?

No

I implemented it on my fork: https://github.com/Wernfried/daterangepicker

A function that is passed each hour/minute/second/am-pm in the two calendars before they are displayed,
and may return true or false to indicate whether that date should be available for selection or not.
Signature: isInvalidDate(time, side, unit)
side is 'start' or 'end' or null for singleDatePicker = true
unit is 'hour', 'minute', 'second' or 'ampm'
Function has no effect on time values set by startDate, endDate, ranges, setStartDate, setEndDate.

Example:

const validRange = [DateTime.fromSQL('2025-03-01 11:30'), DateTime.fromSQL('2025-04-21 18:30')];

isInvalidTime: (time, side, unit) => {   
   if (side == 'start' && time.hasSame(validRange[0], 'day')) {
      if (unit == 'hour') {
         return time.hour < validRange[0].hour;
      } else {
         return time.hasSame(validRange[0], 'hour') ? time.minute < validRange[0].minute : false;
      }
   } else if (side == 'end' && t.hasSame(validRange[1], 'day')) {
      if (unit == 'hour') {
         return time.hour > validRange[1].hour;
      } else {
         return time.hasSame(validRange[1], 'hour') ? time.minute > validRange[1].minute : false;
      }
   } else {
      return false;
   }
}
