Remarks

A DATE, or Variant Time Object, is stored as an 8-byte real value (double) representing a date between January 1, 100 and December 31, 9999, inclusive. The value 2.0 represents January 1, 1900; 3.0 represents January 2, 1900, and so on. Adding 1 to the value increments the date by a day. The fractional part of the value represents the time of day. Therefore, 2.5 represents noon on January 1, 1900; 3.25 represents 6:00 A.M. on January 2, 1900; and so on. Negative numbers represent the dates prior to December 30, 1899.
