The length of day on Mercury is 58.646 Earth days. That's the rotation time,
which is the sidereal day, but there's also the solar day.
The solar day on Mercury is 176 Earth days.
Mercury rotates in about 58.65 Earth days. That's called a sidereal day.
Mercury has a "solar day" which is 3 times as long at about 176 Earth days.
So there are two answers :
Sidereal day: about 58.65 x 24 hours
That's about 1408 hours.
Solar day: about 176 x 24 hours.
That's about 4224 hours.
58.6 Earth days
what is mercurys leth of day
About 1,400 hours, or 59 Earth days.
Mercury.
Mercury is the closest planet to the Sun in our Solar System. It rotates very slowly on its axis. The length of one day on Mercury is equal to 58 days, 15 hours and 30 minutes on Earth.
One Mercury Day is the equivalent of 59 earth days.
To understand the length of a day on Mercury, it is important to know the length of a Mercurian year. (Actually you don't need to know that.) Mercury orbits the sun in about 88 Earth days. It rotates on its axis (day) three times for every two orbits around the Sun (year). A Mercurian year lasts about one and a half Mercurian days. That's about 58.65 Earth days for the length of a day on Mercury. Remember though that this is called a "sidereal day". There's also another day called the "solar day". This is based on the apparent journey of the Sun round the sky. For Earth these two days are only slightly different, but for Mercury the difference is huge. The solar day is about 176 Earth days on Mercury.
58.6 Earth days x 24 for hours

Mercury rotates once in about 58.6 Earth days. That's one definition of its day. However, Mercury's "solar day" lasts about 176 Earth days. That "day" is based on the position of the Sun in the sky. It depends on Mercury's orbital motion as well as its rotation on its axis.
One day on Mercury is equal to 1407.6 Earth hours.
One year on Mercury is about 88 Earth days long, 3/4 of a Mercurian day.
coz of how it obsorves with the sun
58.6 Earth days x 24 for hours
The sidereal rotation period (e.g day) of Mercury is 58.646 days.Mercury's orbital period (e.g Year) is 87.969 days.The combination of this rotation (spinning) and its orbital motion is that the "solar day" on Mercury (sunrise to sunrise) would be about 176 Earth days, and the Sun would not appear to move at a constant rate across the Mercury sky.See related link for more information.58 days and 19 hoursthe length of one day on mercury is 58.646 earth days
