First, determine the opening hours according to the number of teaching weeks:

1. There are about 40 weeks of teaching time in each academic year, the specific number of weeks depends on the regulations of the state and local education administrative departments, and the opening hours of primary and secondary school libraries are also based on the weekly teaching time.

2. Under normal circumstances, primary and secondary school libraries will be opened at noon and after school on the official teaching day every week to meet the reading needs of students at different time periods.

Second, the benefits of primary and secondary school libraries:

1. How open is it to strengthen reading promotion? Reading education has become an important part of school education, and schools are actively promoting reading. In this context, the opening hours of primary and secondary school libraries should be appropriately expanded to provide more reading opportunities and promote the formation of school reading atmosphere.

2. Improve reading interest: On holidays or weekends, if conditions permit, primary and secondary school libraries can expand their opening hours to attract more students to read. A series of cultural activities and reading promotion activities such as reading sharing meetings and holiday reading challenges can be carried out to enhance students' reading interest and ability.

3. Make full use of modern scientific and technological means to provide online resources: With the popularity of the Internet, primary and secondary school libraries can broaden students' reading choices and meet the needs of online reading by providing online books, knowledge videos and other resources. At the same time, primary and secondary school libraries should also have certain digital service capabilities, such as digital book lending and e-book reading, in order to keep up with the pace of the times.

4. Reasonable arrangement of opening hours: Reasonable opening hours of primary and secondary school libraries will help to improve students' interest and love for reading, thus improving students' reading ability and academic level. Defining the opening hours and regulations can help students plan their reading time reasonably and arrange their study life scientifically. The opening hours of libraries are usually coordinated with other cultural facilities, such as sports facilities and science and technology museums, to meet the different development needs of students.
