    Metadata details:
    filename: weeks_in_period_counter.rb
    path of file: ./repos/i-diario/app/services
    
    the code of the file until where you have to start completion: class WeeksInPeriodCounter
  def self.count(start_d
    
  def count
    week_counted = false
    weeks = 0

    (@start_date..@end_date).each do |date|
      week_counted = false if date.monday?
      next if week_counted || is_weekend?(date)
      weeks += 1
      week_counted = true
