In that year, it is usually necessary to fill in the specific time period, indicating the activity time of a person or organization in a certain field or industry. The specific filling method depends on the type and requirements of the application or report submitted.

For example, when filling out a job application, you need to fill in the "year", and you need to fill in the time period of your company or unit, such as 20 19 1 to 2020 12. If "year" is required when filling in the financial report, the specific time period of financial activities involved in the report should be filled in, such as 20 19 1 to 20 19 12.
