Run by amateur enthusiast Steffen Thorsen, the Time and Date website provides a number of tools for calculating times and dates, including calendars and world clocks relating to the current year as well as historical and future years. The variety of tools can be confusing, but they are simply laid out and easily customised, particularly after free registration. A calendar can be created for any year and customised to show the phases of the moon or the holidays in various countries. Calculator tools allow the user to find out the duration between any two dates. Current time tools workout the time in major cities worldwide. An attractive world map shows which parts of the Earth are currently in daytime and night time. The user can compare time zones between cities and calculate a suitable time to make international conference calls. There is a countdown to New Year 2008 and tools to create a customised countdown to any date. The user can find out which code is needed to make international calls from many countries and to calculate the distances between cities.
