## What is Horzono Time Zones?

Master your timezones with ease:
• Instantly see which hours overlap between your location and up to four places elsewhere on the world.
• Know in seconds what time it is in your place when it is e.g. 9 am in another country or state.
• Understand if it is earlier or later in the day at another place, compared to where you are: locations are plotted on the world map and daylight or darkness is shown.
• Drag the map or the coloured bars (indicating availability) to find optimal time slots for virtual meetings.
• All 31 different time zones and 16 different daylight saving time regimes are automatically taken care of behind the scenes. Even if you select a future date to see what this means for overlapping business hours.
• Works always, even in airplane mode. No WiFi or mobile internet needed at all, to still always know the correct time of any location globally that you need.



Ideal when working with people in other timezones or traveling to other countries. Download Horzono today on your iPhone!

### 4/5 — One change and it’ll be perfect…

*2023-03-28*

Solid, easy to use app.   BUT no ability to have a GMT/UTC time (without fiddling w/ DST).  That’s a really useful capacity for some of us WHO routinely use it for work.

**Developer response:** Thank you very much for your review. The location "UTC / GMT" was added in the May 2023 1.2 release and shows the same universal time all year round. Apologies for not notifying you earlier.

### 5/5 — Simple & Handy

*2022-01-19*

Very nice and handy visualisation of time zones.
