31,536,000

[Calendar]  The number of seconds in a calendar non-leap (365-day) year.

31,536,855

[Math.]  A pair of amicable numbers (31536855, 32148585).

31,556,925

[Astronomy]  Tropical year = 31,556,925.4752 seconds = 365 days 5 h 48 m 45.48 s. Sidereal year is the time interval that the Earth returns to the same place in its orbit relative to a fixed star, 31,558,149.504 seconds = 365 days 6 h 9 m 9.5 s. The sidereal year is longer than tropical year because of the slow westward shift of the equinoctial point along the plane of the elliptic at a rate of 50.27 seconds of arc per year. Anomalistic year is 365 days 6 h 13 m 33 s.

31,557,600

[Calendar]  The average number of seconds in a Julian calendar year.

31,558,149

[Astronomy]  Sidereal year is the time interval that the Earth returns to the same place in its orbit relative to a fixed star, 31,558,149.504 seconds = 365 days 6h 9m 9.5s. Tropical year = 31,556,925.4752 seconds = 365 days 5h 48m 45.48s. The sidereal year is longer than tropical year because of the slow westward shift of the equinoctial point along the plane of the elliptic at a rate of 50.27 seconds of arc per year.

xy,abc,def

[Math.]  For any xy = 10 to 99, there are always six 6-digit numbers abc,edf such that the sum (xy+abc,def) is equal to one of 6 digit-rotations of 142,857 and the number xy,abc,def is a multiple of 142,857.

For any xy = 10 to 99, there are always twelve 6-digit numbers abc,edf such that the sum (xy+abc,def) is equal to one of 12 digit-rotations of 076,923 or 153,846 and the number xy,abc,def is a multiple of 76,923.
