Sequential time


A sequential time is one in which the numbers form a normal sequence, such as 1:02:03 4/5/06. Short sequential times such as 1:23:45 or 12:34:56 appear every day. Larger sequential times rarely appear, such as 12:34:56 7/8/90, or 01:23:45 on 6/7/89. These times can be dependent on the date format being used; the month/day format will produce different results from the day/month format.
This term, however, is not limited to simple counting. Other sequences, such as the decimal numbers of the mathematical constants pi|, E |, and the square root of two are also noted. Number sequences such as the Fibonacci sequence can also be found in time stamps.
These dates are particularly popular with couples getting married who are seeking unique wedding and anniversary dates. Dates with repeating numbers such as July 7, 2007 "7/7/07" are also popular.
Palindromic times can also be observed, e.g. 10:02:10 on 11/01/2001 was the first fully palindromic time sequence of the twenty-first century. The next palindromic time sequence will be at 02:02:10 at 11/01/2020.
A sequential time occurred during Pi Day on 3/14/15 at 9:26:53.58979... following the sequence of pi to all digits.
