Julianator4.7 - App Store
You'll be able to see results in few seconds.
Publisher Description
This app converts a date between Julian Day of Year and Gregorian. For example, September 11, 2022 converts to 2022-254 and 2022-254 converts to September 11, 2022.
This app will convert both directions.
Julian Date for this app refers to the day-of-year number (more properly, the ordinal date) in the Gregorian calendar, often used in mainframe computer systems, the military, and the food industry. (Note: this app does not used the term Julian Date to refer to the astronomy definition which is calculated from 4713 BC)
Features a simple clean interface with pickers for the dates.
The app also features a monthly view allowing a quick view of both Gregorian and Julian days for the entire month.
Widgets are available for both the Home Screen and the Lock Screen to display the current day of year.
A Watch app is available that includes a date converter and complications to display the current day of year.
Note: The app's icon does not change to reflect the current day.
