  def school_term_day?(school_term_type_step, date, classroom = nil)
    step = classroom.present? ? StepsFetcher.new(classroom).step_by_date(date) : step(date)

    return if step.blank?
    return if step.school_calendar_parent.steps.count != school_term_type_step.school_term_type.steps_number

    step.step_number == school_term_type_step.step_number
