    save static data without adding new data or editing it?
    What are the requirements for accessing the data written to the file/DB?
    Is the file written all at one time? Can it all be contained in memory?

    hat are the requirements for accessing the data written to the file/DB? yes i need just read data and show in a label daily
    Is the file written all at one time? yes it is written one time for use
    Can it all be contained in memory? In fact, daily occasions are recorded in the database and the occasion of each day should be displayed on a specific day, for example, 2020/12/25 shows the Christmas day in label.
    Occasions for the Gregorian, Hijri and Jalali dates are simultaneous like this
    1400/01/01 must show eyde noruz
    1442/01/01 must show first day of hijri
    2021/01/01 must show first day of Gregorian
    but 2021/01/01 = 1399/10/12 Jalali and = 1442/05/17 Hijri, Each of which has its own occasion
    Meanwhile, the difference between these dates changes every year
    All three occasions must be displayed on the same label at the same time, and there may be several occasions in a day For each of the calendars Or there is no opportunity for one, two or all three of them

    Is the file written to more than one time? In other words, the file is created and filled with data all in one go and never written to again.

    How large is the file? Can all of it be read and saved in memory say in some kind of collection?
    If you don't understand my answer, don't ignore it, ask a question.

    For a file that small ( 24 k size), read it in, parse it into the desired types and store it in a collection where it can be easily accessed as needed.
