Stop converting time in your head! See local, military, and UTC time (GMT and Zulu time zones) with a tap. Developed by pilots who can never remember the current UTC (GMT/Zulu) time conversion, Pilot Time instantly gives you the current time and date for your zone, plus UTC time. Pilot Time can: - Compare the time and date at your current location (in 12-hour format and 24-hour format) to UTC time. - Show the 3 time zones you looked at most recently, plus UTC time. - Quickly convert any past, current, or future time to or from any time zone (including GMT). And selecting time zones is easy: first find the continent, then the city you want. No more mental calculations. (The time is provided by your phone's operating system, not a central server. Time zones are taken from the IANA Time Zone Database.)

Verdict
The clearest difference is price: Pilot Time at Free against 365 Days Calendar's $1.99. Pilot Time also leads on iOS requirement (13.0 vs 17.6). 365 Days Calendar's advantage is update cadence (every 2 months vs every 6 months) and rating (4.7 vs 4.5). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.
