I wish it would auto refresh every time it opened. Ex: if you opened the app yesterday and click it again today without force-closing, it will show still have yesterday highlighted as today. ### 5/5 — App idea *2026-03-18, version 2019.1* Consider live julian date on app icon so it is quickly visible. Like the apple clock, you can see without opening app. Icon shows 330 jd. ### 5/5 — Watch Complication is Amazing! *2025-02-17, version 2019.1* I saw a lot of mixed reviews on this but decided to give it a try for myself. I'm an Air Force pilot and use the Julian date to verify the currency of maintenance when doing my preflight. Having today's Julian date on my Apple Watch face is a total game changer. Thank you for the work you put into this app! ### 4/5 — App Still Works on 18.1.1 but widget isn’t available *2024-12-01, version 2019.1* Nice app but looks like abandonware. Still functional on 18.1.1 but no more widget functionality. ### 4/5 — Works but needs fixed on Apple Watch *2024-10-13, version 2019.1* Excellent app which I use daily as a lab technician. Please update this app for the Apple Watch 10, the complication will not display the date and just says “Julian”. Other than that, great app! ### 5/5 — Love it!! *2024-09-24, version 2019.1* Very helpful, I use this calendar everyday for work. ### 5/5 — La mejor *2024-09-18, version 2019.1* Tengo años de utilizarla, me es muy útil en mi trabajo 🫶🏻 gracias ### 5/5 — Excellent *2024-09-16, version 2019.1* Simple et exactement ce que je cherchais! ### 1/5 — Not accurate *2024-03-16, version 2019.1* When the Julian calendar switched to Gregorian in Oct 1582 ten days were subtracted due to their calculations which were the reason for switching calendars. Also the first day of the year in the Julian calendar was the first full moon in april and it was always a monday. ### 5/5 — Calendar *2024-01-30, version 2019.1* Great easy to read app! Thanks! ## Frequently asked questions about Julian ### What does Julian do? Julian is a utility app that allows you to view and convert between 11 different types of dates.
