The Julian Date Tool Pro version shows the Gregorian Date and the ISO-8601 Ordinal Date, also known colloquially as the "Julian Date". The actual "Julian Date", used by astronomers is displayed.
Plug in any date and the Ordinal Date and Julian Date will be calculated.
Also included is the Latitude and Longitude of your phone's current location. Coordinates change automatically when the phone is moved.
The Julian Date Pro version also includes: Bi-directional, automatically recalculating conversions of Gregorian Date to Ordinal Date, Astronomical Julian Date, Modified Julian Date and Julian Day Number; also a Date Selection Tool AND a calculator for determining the number of days between two dates. That's a Big Bang for your buck!
