Time

I have created a Wikidiary on time. Well, it's mostly about time anyway. For those wishing to edit an article on time, but with little to go on, it is located here: User:Dessydes/Space, Time, and Spacetime. Dessydes 23:59, 12 August 2006 (UTC)[reply]

Time and/or Date Algorithms

I don't see anything on the Category page for those seeking information on Time and/or Date algorithms.

I don't mean "analogue" algorithms, for precision measurement of time, sidereal time, etc.; I mean "exact" ones based on well-defined calendars/clocks such as the Gregorian, the Julian, (both the Secular Calendar and the Date of Easter), ISO Week Numbering, Time of Day with allowance for Summer Time and Time Zone.

I would include links, if available, for other Calendars where well-defined and in actual use.

Algorithms would include Zeller's Congruence and ones for converting between UTC Y M D and [Modified] Julian Date and between Civil Y M D and Chronological [Modified] Julian Date and similar for ISO Y W D. They should be expressed in higher-level pseudo-code, so that they can readily be implemented in any language.

Such a page would probably best not go into details of the algorithms themselves; it would largely be a routing page leading to existing and maybe new material.
