maxDate = moment.utc().add(90, ‘d’).format(‘YYYY-MM-DD’);
minStartDate(): string {
return moment().format(‘YYYY-MM-DD’);
minEndDate(): string {
return moment(this.startdate).add(0, ‘day’).format(‘YYYY-MM-DD’);
changeEndDate(): void {
if (moment(this.startdate).isSameOrAfter(this.endDate)) {
this.endDate = moment(this.startdate).add(0, ‘day’).format(‘YYYY-MM-DD’);
