let startDate: string = "2020-01-12";
let enddate:string="2023-11-01";
let date1: Date = new Date(startDate);
let date2: Date = new Date(enddate);
let timeInMilisec: number = date2.getTime() - date1.getTime();
let daysBetweenDates: number = Math.ceil(timeInMilisec / (1000 * 60 * 60 * 24));
console.log(Math.ceil(daysBetweenDates/365));
