def _compute_hours(self):
       for date in holidays.BD(years=[2022, 2023, 2024, 2025]).items():
           print(str(date[0]))
       if self.start_date and self.date_deadline:
           t1 = datetime.strptime(str(self.start_date), '%Y-%m-%d')
           print(t1)
           t2 = datetime.strptime(str(self.date_deadline), '%Y-%m-%d')
           print('=================================T2')
           print(t2)
           t3 = t2 - t1
           delta = timedelta(days=1)
           count = 0
           while t1 <= t2:
               print(t1.strftime("%Y-%m-%d"))
               t1 += delta
               if t1.weekday() in [5, 6] and date.days():
                   print('holiday')
                   count += 1
           print("total holidays", count)
           # count = sum(1 for day in t3 if day.weekday() < 5)
           # print(count)
           print('=================================T3')
           print(t3)
           print('=================================')
           seconds = t3.total_seconds() / 3
           diff_in_hours = seconds / 3600
           print('Difference between two datetimes in hours:')
           # print(diff_in_hours)
           self.total_hours = diff_in_hours - (count * 8)```
