## Julian Clock Description
It's as simple as it gets, a Julian date and clock app built for people who need the numbers fast.

Julian Clock shows everything you need at a glance:

• Julian date (YJJJ or YYDDD, your choice in Settings)
• Local time with running seconds
• Date in military format (e.g. 19JUN26)
• Day of the week
• Zulu time (GMT)

New in version 2

• Home Screen widgets — small and medium layouts with Julian date, Zulu, and military date
• Lock Screen widgets — circular, rectangular, and inline at-a-glance views
• Apple Watch app — Julian date and Zulu on your wrist, plus complications
• iPad support — universal layout for desk and EFB use
• Historical lookup — pick any date on the calendar to get its Julian day
• Eight themes — Navy, Air Force, Army, Marines, Coast Guard, Space Force, Dark, and Light

Widgets and the Watch app stay in sync with your format and theme choices.

This app is for military and DOD personnel who constantly need a quick look at the Julian date and/or Zulu time, on the phone, on the lock screen, on the watch, or on an iPad beside the job.

Worked great when I was in the military, and private sector when I needed the Julian Date.

### ***** "Great"
This is perfect and Simple. 
I agree with the other reviews, a widget for the lock screen would be great.

### ***** "Perfect!"
This app does what it's supposed to. No troubles at all. Very fast and convenient.
-- 737852147907532135780, 2016-05-26

### ***** "Perfect!"
I was originally looking for an app that displayed the current Julian day on the app icon like the regular calendar, but was having no luck. This one works great and quickly opens to show all the Julian day information and is in military format which is great. It updates daily without having to select anything.
-- Rodzillaxx, 2016-02-03

### ***** "Must have for military pilots!"
Super convenient! Must have for all military pilots! Wish there was an iPad version for the EFBs!!
