I was a student when I was in college. I didn't take part in the work and had no salary, so I couldn't calculate the length of service. If a university graduate is employed, the length of service shall be calculated from the date of employment. Nowadays, calculating the length of service is not as important as it was before the reform of the labor system, and the calculation of social insurance benefits is based on the payment period.

The length of service of fresh graduates is calculated from the starting time of actually taking part in work and paying social security, that is, the accumulated working hours add up to the length of service, excluding the period interval. Here is divided into file length of service and working length of service.

Length of service refers to the working time when employees take wage income as their whole or main source of livelihood. The length of service marks the length of time employees have been working, and also reflects their contribution to society and enterprises, as well as the level of knowledge, experience and technical proficiency.

There are two kinds of service years:

1, the file length of service is generally applicable to state enterprises, institutions and government agencies, and can be calculated cumulatively from handling personnel agency to retirement;

2. Length of service is generally applicable to ordinary enterprises and private units. Calculated by the time of handling social security. If you stop paying insurance (stop working) halfway, you will also stop accordingly. After returning to work, the length of service will continue to accumulate.

There are three ways to calculate the length of service:

1, continuous calculation method: refers to the calculation period of the employee's work unit after the enterprise goes through the formalities of change, merger or division according to law. In this case, the length of service of workers should be calculated continuously, and the new employer should bear the responsibility for the length of service of workers in the original employer, that is, the length of service of workers should be calculated directly and continuously, regardless of other factors;

2. Consolidated calculation method: refers to the consolidated calculation of two working hours before and after a period of interruption due to subjective and objective reasons. If the retired workers are streamlined, the continuous working hours before retirement and after rejoining the work can be calculated together;

3. Length of service conversion method: the continuous length of service of workers engaged in special types of work and special working environment can be converted. If you work in a bad working environment, every year you work in such a place can be counted as one year and three months when calculating the continuous length of service. Workers directly engaged in work harmful to health shall be counted as one year and six months for each full year of continuous service. For example, when calculating the continuous length of service of underground miners, every year of working in harsh environment can be counted as one year and three months.

To sum up, the length of service is calculated according to the social security paid by employees, and the length of service has a certain relationship with receiving pensions in the future.

Legal basis:

Article 9 of the Regulations for the Implementation of the Labor Contract Law of the People's Republic of China

The starting time of continuous work 10 year stipulated in the second paragraph of Article 14 of the Labor Contract Law is calculated from the date of employment by the employer, including the working years before the implementation of the Labor Contract Law.

Article 10

If a laborer is assigned to work in a new employer for reasons other than his own, the working years of the laborer in the original employer shall be calculated as the working years in the new employer. If the original employer has paid economic compensation to the employee, the new employer will not calculate the employee's working years in the original employer when dissolving or terminating the labor contract according to law.
