A '''time horizon''', also known as a '''planning horizon''', is a fixed point of time in the future at which point certain processes will be evaluated or assumed to end. It is necessary in an [[Accountancy|accounting]], [[finance]] or [[risk management]] regime to assign such a fixed horizon time so that alternatives can be evaluated for performance over the same period of time |

Although short term horizons such as [[end of day]], end of week, end of month matter in accounting, generally it is mere summing-up and the simplest [[mark to market]] processes that take place at these short term horizons. No [[scenario analysis]] or mark to future activities are usually undertaken for such short periods, except for very large portfolios. |

The most common horizons used in planning are one "quarter" (a quarter year, or three months), a year, two years, three years, four years (especially in a [[representative democracy]] where this is a quite common [[term of office]] and election cycle) and five years (in corporate planning). More far-sighted companies and government agencies may also use between ten and one hundred years.

Agreeing on a common time horizon for action is particularly important in global policy, as each participant will have very different time horizon habits. Achieving [[simultaneous policy]] is quite difficult without an agreement, as those taking action early may be seriously disadvantaged in competition with those taking action late on a regulatory matter. One attempt to bring about a global simultaneous policy is being attempted by the [[International Simultaneous Policy Organization]]'s SIMPOL campaign.<ref name="Campaign concept">[http://www.simpol.org.uk/index.php?id=8 Simpol.org - Campaign concept]</ref> |

Also, in terms of physics, the term "time horizon" is also synonymous with [[event horizon]], first identified in [[Stephen Hawking]]'s [[A Brief History of Time]].{{Citation needed|date=May 2011}} Hawking stated that the time horizon is the boundary that separates a [[black hole]] from other celestial bodies. Even time and light cannot escape once trapped in the black hole. |
