firstDayOfWeek:3,
shortcuts: [{
text: '最近一周',
onClick(picker) {
const end = new Date();
const start = new Date();
start.setTime(start.getTime() - 3600 * 1000 * 24 * 7);
picker.$emit('pick', [start, end]);
}
}, {
text: '最近一个月',
onClick(picker) {
const end = new Date();
const start = new Date();
start.setTime(start.getTime() - 3600 * 1000 * 24 * 30);
picker.$emit('pick', [start, end]);
}
}, {
text: '最近三个月',
onClick(picker) {
const end = new Date();
const start = new Date();
start.setTime(start.getTime() - 3600 * 1000 * 24 * 90);
picker.$emit('pick', [start, end]);
}
}]

value1: '',
value2: ''

};
var Ctor = Vue.extend(Main)
new Ctor().$mount('#app')

What is Expected?

设置firstDayOfWeek为2或者3，日期选择正常，不会顺延7天

What is actually happening?

设置firstDayOfWeek为2或者3，日期选择正常，会顺延7天；例如：选择2023-08-06到2023-08-06实际显示的值是2023-08-13到2023-08-13，选择2022-02-06到2022-02-06实际显示的值是2022-02-13到2022-02-13
