Exact time in cities and countries of the world

Do you want to know what time it is right now in another city or country? Are you planning a trip, a business meeting, or a call abroad? Are you interested in different time zones and their features? Then you’ve come to the right place!

Our website provides you with accurate time in any city or country in the world. You can easily find the desired city or country using the name search. You can also find out the date, day of the week, season, sunrise, and sunset in the selected location.

Our website constantly updates time information, taking into account daylight saving time changes and other adjustments. Our website is your reliable and convenient source of accurate time worldwide!

How we ensure time accuracy

The time on our server is synchronized with high-precision reference time from the TimeNL project (ntp1.time.nl, ntp2.time.nl, ntppool1.time.nl, ntppool2.time.nl). These are real Stratum 1 servers, directly connected to several independent sources: GPS, Galileo, the DCF77 radio signal, and atomic clocks in the Netherlands and Belgium. Without exaggeration — one of the most reliable and accurate public sources in Europe.

We use TimeNL specifically because our hosting server is located in the Netherlands (geographically closest to them). Actual measurements from the server console show a round-trip delay of 4–6 ms, which ensures minimal network latency and maximum accuracy and stability of synchronization.

On the page itself, the time is updated after all elements are fully loaded. We use lightweight AJAX requests: we record the time the request is sent, the time the server response is received, obtain the timestamp, and adjust it with special algorithms considering network latency. Thanks to this, you see very precise current time — usually with an error of only a few tens of milliseconds. This is real accuracy on the regular Internet without special equipment. For comparison: the average time of a single eye blink is about 100–400 milliseconds — which is already greater than our error margin.

And about the “synchronization with atomic (cesium) clocks” that some websites love to promise…

Let’s figure out how it actually works:

Accurate time starts with reference clocks. These devices are based on the most stable physical processes — atomic oscillations. Most often, cesium atomic clocks are used. They provide fundamental accuracy and serve as the basis for the international definition of the second (1 second = 9 192 631 770 oscillations of radiation corresponding to the transition between two levels of the ground state of the cesium-133 atom). Such devices are called Stratum 0 — they are not network nodes, but the physical sources of time themselves.

Then special servers, called Stratum 1, synchronize directly with the reference clocks. They have a direct connection to Stratum 0. These servers become the primary sources of time in the network and distribute it further to other systems. It is with these servers that our server synchronizes.

The next level is Stratum 2. These are servers that receive time from Stratum 1. They do not have direct access to the reference clocks but synchronize with several primary servers to increase reliability and resilience.

To truly have synchronization with cesium clocks, a website must either be a very important government project or its owner must be Elon Musk, who can afford it. And judging by the amount and type of advertising, it is quite difficult to claim this. Then it is up to you to decide how much you can trust the rest of the content on such websites.

We prefer honesty and real technologies rather than beautiful fairy tales.
