Python:

import random
import datetime
start_date = datetime.date(2000, 1, 1)
end_date = datetime.date(2023, 12, 31)
random_date = start_date + datetime.timedelta(days=random.randint(0, (end_date - start_date).days))
print(random_date)

JavaScript:

const startDate = new Date(2000, 0, 1);
const endDate = new Date(2023, 11, 31);
const randomDate = new Date(startDate.getTime() + Math.random() * (endDate.getTime() - startDate.getTime()));
console.log(randomDate.toDateString());

Java:

import java.time.LocalDate;
import java.time.temporal.ChronoUnit;
LocalDate startDate = LocalDate.of(2000, 1, 1);
LocalDate endDate = LocalDate.of(2023, 12, 31);
long days = startDate.until(endDate, ChronoUnit.DAYS);
LocalDate randomDate = startDate.plusDays(new Random().nextInt((int) days + 1));
System.out.println(randomDate);

C#:

using System;
DateTime startDate = new DateTime(2000, 1, 1);
DateTime endDate = new DateTime(2023, 12, 31);
Random random = new Random();
TimeSpan timeSpan = endDate - startDate;
TimeSpan randomSpan = new TimeSpan((long)(random.NextDouble() * timeSpan.Ticks));
DateTime randomDate = startDate + randomSpan;
Console.WriteLine(randomDate.ToShortDateString());
