input: Write a python function to calculate the difference in years, months, and days between two given dates in "YYYY-MM-DD" format.
  assert calc_diff("1989-09-26", "1997-03-15") == (7, 5, 17)
  assert calc_diff("2000-01-01", "2020-01-01") == (20, 0, 0)
  assert calc_diff("2010-06-15", "2015-08-25") == (5, 2, 10)
output: from datetime import datetime
  
  def calc_diff(date1, date2):
      d1 = datetime.strptime(date1, "%Y-%m-%d")
      d2 = datetime.strptime(date2, "%Y-%m-%d")
      
      delta = d2 - d1
      total_days = delta.days
      
      years = total_days // 365
      days_remaining = total_days % 365
      months = days_remaining // 30
      days = days_remaining % 30
      
      return years, months, days
