Legal analysis: the tax bureau does not issue invoices on weekends. According to the laws of our country, legal holidays are rest days, state organs and institutions implement unified working hours, and Saturday and Sunday are weekly rest days. Enterprises and institutions that cannot implement the unified working hours stipulated in the preceding paragraph may flexibly arrange weekly rest days according to actual conditions.
Legal basis: Article 7 of the Regulations of the State Council on Working Hours of Employees stipulates that state organs and institutions shall implement unified working hours. Since the implementation of these regulations, Saturday and Sunday in the first week are rest days, Sunday in the second week is rest days, and so on.
