系统是否提供了判断两个Date日期是否是同一周的方法？

import I18n from '@ohos.i18n';  
  
calendar: I18n.Calendar = I18n.getCalendar("zh-Hans");  
  
aboutToAppear() {  
  this.calendar.setFirstDayOfWeek(4);  
  this.calendar.set(2024, 2, 19, 8, 0, 0);  
  this.weekYear1 = this.calendar.get("week_of_year");  
  
  this.calendar.set(2024, 2, 20, 8, 0, 0);  
  this.weekYear2 = this.calendar.get("week_of_year");  
  
  const isSameWeek = this.weekYear1 === this.weekYear2;  
}
