iDateConvL (aka iDateConvert Lite) is the free version of iDateConvert, a simple but extensive utility for converting dates between different actual and historical calendars. This fully functional lite version implements 10 calendars (the Gregorian, Julian, Chinese, Arithmetical Islamic, Hebrew, Old Hindu Solar, ISO and Roman Calendar, as well as the Julian and Modified Julian Day Number) out of more than 50 calendrical and day numbering systems which can be found in the full version iDateConvert.
USE and FEATURES:
The use of iDateConvL should be straightforward. The default conversion pane ('Date Conversion') allows to choose the source and target calendar for conversion, and provides a short description (via the 'Info' button) for each selected calendar. Due to size limitations of the iPhone interface, default date selection by numbers only is provided within a reasonable range between year -10, 000 and 10, 000 in the Gregorian Calendar. However, as many calendars work with names (not numbers) for their various components, an alternative date selection method can optionally be chosen in the 'Preferences' pane. Individual calenders can be enabled or disabled in the 'Preferences' pane as well. Finally, in addition to the default date conversion interface (via 'Date Coversion'), a clean list of converted dates for all enabled calendars is provided by selecting 'Date List' in the bottom menu.
NOTE concerning calendrical conversions:
Despite countless attempts in the past and present to standardize the various calendrical systems in existence, exact conversions are still subject to many variations and local rules, which render calendrical conversions a rather tedious and difficult task. The calendrical algorithms used in iDateConvert Lite/iDateConvert are implemented from mostly original sources, and checked for correctness using 'Calendrical Calculations' (3rd Edition) by Bachum Dershowitz and Edward M. Reingold, the to-date most comprehensive and clear description of modern and historical calendrical systems. Although we tried to follow the most commonly accepted algorithmic definitions and nomenclature, we welcome each report of inconsistencies or errors for improving the usability of iDateConvert Lite/iDateConvert.
We hope you enjoy the use of iDateConvert Lite, or its full implementation iDateConvert.
