From 9 Users to Millions

The first version of the World Clock was developed as a university project in only 2 days. The first external visitor viewed the service at 1995-11-07 16:03:54 UTC. The page had a total of only 9 (!) visitors on the first day, and 20 visitors during the next day. The traffic remained at that level for the rest of November 1995. Today, timeanddate.com has more than a million users every day.

The very first edition did not account for changes due to Daylight Saving Time. This was fixed in January 1996, and that first upgrade featured a list of current times in around 120 cities.

English Second

Initially, the World Clock was available in Norwegian only, but the English version was implemented shortly after, on November 19, 1995.

During the World Clock's first years, the service ran on the author's Unix account at the University of Trondheim (later renamed NTNU).

In December 1995, the World Clock was listed on Yahoo, which provided an increase in traffic and more international visitors. Its popularity increased during the next few years. The URL back then was http://www.stud.unit.no/USERBIN/steffent/verdensur.pl.

1998 – 2015

In May 1998, timeanddate.com became available online after one year of development. It aimed to replace the old version of the World Clock and other services that were still on the university account.

It featured more cities and new services such as the Personal World Clock and the Meeting Time Planner. More services and enhancements were added on the website during these years. The Updates page has more details.
