Store listing

Full description
A simple calendar that displays a whole month of both standard (Gregorian) and Julian days together in the same display for easy conversion between the two. Useful to those who work with Julian dates e.g., mainframe programmers and schedulers. Features: >Shows a full month at a time of Julian date/normal date and optionally week number. >Optional Widgets showing the current Julian day. >Week of year display >optional landscape mode enable via settings >Can be installed on SD card IF not using widgets. (Note: widgets only available for installs not on SD cards or other no default app storage locations due to android limitations) >Besides the default display of date and Julian Day in each calendar cell, you can now display just date, or just Julian day by itself, or combined with the 'week of year number' in any combination of 1 ,2 or all 3. (this was added in response to user request) Note: Displays of all 3 items day/Julian day /week of year number may not be suitable on smaller screens. That said each display mode can have its font size adjusted and saved via menu option. To distinguish between the 3 types of information, Julian days will always by bounded by a "-" e.g. -123-, and week number will always be in brackets e.g.(30). Long press can be set to open calendar/agenda on the device. Works only for the latest android. Enabled via settings.
