several calendar devices is an awkward addition to the design challenges. the main basic principle is that a lot of end users want the normal ISO calendar program. as a result, the most crucial courses are ISO-only. the 2nd principle is that the majority of of those that want a non-ISO calendar process want it for user conversation, Hence It is just a UI localization concern. therefore, day and time objects need to be held as ISO objects in the information design and persistent storage, only remaining converted to and from an area calendar for Screen.
