What should I do if the mahjong calendar is not allowed

Mahjong calendars are not allowed to be changed into ordinary calendars to view calendars. According to relevant information, the mahjong calendar consists of four sub-tables. In the upper left corner is the annual transportation table, in the upper right corner is the monthly transportation table, in the lower left corner is the daily transportation table and in the lower right corner is the time transportation table. It is not easy for the elderly to understand, so it is a feasible method to change to an ordinary calendar, which is easy to understand.
