First, it is usually stipulated in the internship agreement or contract to determine the start date and end date of the internship. If there are vacations or other special circumstances during the internship, it is necessary to exclude these hours from the internship. If the internship is full-time, then the internship time should include working days and weekly working hours. If the internship is part-time or flexible, it can be filled in according to the actual time period and working hours. When filling in the internship time, make sure to accurately reflect the actual participation in the internship to avoid any misleading or inaccurate information. If in doubt, it is recommended to consult the internship unit or the relevant human resources department to ensure that the correct internship time is filled in.
