This template, {}, calculates an Earth date and time that correspond to a given day and time on Mars for an event in the NASA Mars 2020 mission of the Perseverance rover and Ingenuity helicopter. The result is shown as a standard calendar date and 24-hour clock time in Coordinated Universal Time (UTC, previously known as GMT).
A convention used by spacecraft lander projects to date has been to enumerate local solar time using a 24-hour "Mars clock" on which the hours, minutes and seconds are 2.75% longer than their standard (Earth) durations.
As Mars2020 touched down mid afternoon local time, a clock started at the time of touchdown would lag between the mission clock by about 15 Mars hours." [use SpaceCraft Event Time (SCET) rather than Earth Received Time (ERT) which may be "off by about 14 minutes"]. in summary, "if you plug the time and date UT 2021-02-18 13:50:00 into an ...

The basic time periods from which the calendar is constructed are the Martian solar day (sometimes called a sol) and the Martian vernal equinox year.The sol is 39 minutes 35.244 seconds longer than the Terrestrial solar day, and the Martian vernal equinox year is 668.5907 sols in length (which corresponds to 686.9711 days on Earth).
The average duration of the day-night cycle on Mars — i.e., a Martian day — is 24 hours, 39 minutes and 35.244 seconds, [3] equivalent to 1.02749125 Earth days. [4] The sidereal rotational period of Mars—its rotation compared to the fixed stars—is 24 hours, 37 minutes and 22.66 seconds. [4]
