<p>PURPOSE:To facilitate the development and diversion of a date processing program using different calendars by constituting a system in such a way that necessary date and day are calculated from date stored in a storage means by means of an instruction from a reception means so as to convert them. CONSTITUTION:At the start time of an operation, a registration part 2 is started, date data is inputted from a keyboard 1 and it is registered in a registration file 3. An input part 5 reads date data from the file 3 and stores it in the stor age part 6. Then, the reception part 8 gives the conversion instruction to an arithmetic operation conversion part 7 when it receives a request on the date. The conversion part 7 reads date data from the storage part 6, executes the conversion processing of the necessary date and day and informs the reception part 8 of the result. Thus, the reception part 8 informs a request source of the date of the converted result. Since the program can obtain an era name, a year and the date by the necessary calendar in an arbitrary place and at arbitrary time in the system, the development and diversion of the date processing program of the system to be used is facilitated by using the different calendars.</p> |
