Time and Dates (astropy.time) — Astropy v7.2.0#introduction
Introduction
The
astropy.timepackage provides functionality for manipulating times and dates. Specific emphasis is placed on supporting time scales (e.g., UTC, TAI, UT1, TDB) and time representations (e.g., JD, MJD, ISO 8601) that are used in astronomy and required to calculate, for example, sidereal times and barycentric corrections. Theastropy.timepackage is based on fast and memory efficient PyERFA wrappers around the ERFA time and calendar routines.All time manipulations and arithmetic operations are done internally using two 64-bit floats to represent time. Floating point algorithms from [1] are used so that the
Timeobject maintains sub-nanosecond precision over times spanning the age of the universe.Printed 2026-06-28.
