An app for calendar/date conversion

iOS and iPadOS
If this has already been fleshed out, and I just haven't found the topic, please forgive me. I have many friends around the world who use different calendar systems, such as the ISlamic, Hebrew/Jewish, Persian and others. I'm not talking about the ability to convert between iCal, Gmail and Microsoft Exchange calendars etc. Is there an app for such conversion? I see an app for the Islamic calendar itself, but I'd like to find one which will actually convert between calendars, showing today's date in several systems as well as a calendar view where I can enter a date in order to convert it between calendars.

Western-Chinese Calendar Converter Day Month January Year Era AD BC Julian CalendarGregorian Calendar This is just the first stage in what I hope to make a full featured converter between any date in the Chinese and Western calendars, including dynasty and reign title information. As it is now, you can convert between the Julian (the system in use up till 1582) and the Gregorian (the system in use from 1582 till the present) calendars and see the Julian day. You can convert from any of these to the Chinese cyclical year, month, and day, as well the solar month and day, with dynasty and reign title.. I have also have links to other sites dealing with Lunar and Western calendars, as well as my own brief description of the Western solar and Chinese lunar calendar systems. NOTE: The conversion between Western and Chinese calendar systems is based on complicated astronomical algorithms which I do not have. I use tables to do the conversion. Western->Chinese Lunar Calendar Enter the Western date you want to convert to its Chinese lunar equivalent. For an explanation on the difference between the Julian and Gregorian calendars, see below. Most likely you will want to use Gregorian calendar, the system in use in most of the world. This converter currently will only work for dates from 1911 to 2050. The page also includes a converter between the day in the Julian Period and the Gregorian and Julian Calendars.
