I have faced the same issue saying date.getMonth is not a function in the console when I click the calendar icon to change the date

        <DatePicker value={this.state.RevisionDate} required={true} onChange=this.handleRevisionDateChanged} />


          private handleRevisionDateChanged(value: Date): void {
                 return this.setState({
                RevisionDate: value
            });
        }

the state variable Revisiondate is a property of Date type, any help?

@dfalling, thanks for this. react-date-picker does not support value as a string, as in documentation. You need to wrap the date in new Date().
