In some embodiments, an integral portion of the base-36 number represents a date value, and a fractional portion of the base-36 number represents a time value. Each base-36 digit may be represented by one of the numerals 0-9 and the letters A-Z. Both digital and analog clocks displaying date and/or time information in which a day is broken into thirty-six increments are disclosed.
