The day is tha basis of the Decimal Time Project, DTP. According to the system time is measured in days and all calculations of time are based on decimal fractions or multiplications of the day. No other units are used. Larger units are tens, hundreds or thousands of days, and smaller ones are tenth-parts, hundreth-parts of thousanth-parts.

In the present our undarstanding of numbers is to a large extent based on units that are either multiplications or divisions on the basis of 10. This is called the Decimal System and it is generally used in measurement and finance, for example. The system of time measurement is really the only system where the decimal system is not generally applied.

A long time ago this was quite understandable while societies were to a large extent based on periodic practices, such as agriculture. In the present very few peoples livelihoods are based upon the seasons and much the less on the traditional division of the day into two times 12. Modern measurements are based on the decimal system and human understanding of time would be much better if calculations of time were alsa based on the metric system.

It is not feasible to divide every day into 24 hours, or 1,440 minutes, or 86,400 seconds! These are not numbers that are easily a basis of calculations. Much less is the year a sensible concept, it being 365.2521 days to be accurate. In this archaic system the units are absolutely not compatible but based on long lost traditions. The months were originally a measurement of the Moon's movements and the week is an old religious division of time and even further removed from modern society.

The fundamental unit of the DTP is called 'Dies', the latin term for the day. This is in accord with the other units of the metric system, the 'Litre', the 'Metre' and the 'Gram'. The other units are based on a multiplication of the Dies by ten, and so forth, of by the division of the Dies by ten and so on. The main units of the system, in addition to the Dies, are a thousand Dies, the kiloDies, and one thousanth of a Dies, the milliDies. These are units people aqquainted with the metric system know well.
