*  A meridian transit occurs when a celestial body crosses an observer’s local north-south line in the sky. That is practically simultaneous with culmination, i.e. the highest altitude for the day. The planets’ meridian transit times in the above linked graphs can be easily transformed for your location. The given times are nearly the same for the central meridians of all time zones, i.e. those evenly divisible by 15° such as 75°, 90°, 105° or 120°. Do not adjust to UT. Simply add to the chart time 4 minutes for each degree west of a central meridian, or subtract 4 minutes for each degree to the east. If on daylight savings time, add an hour.

NOTE:  Decimal coordinates are posted in the ephemerides to ease interpolation, since few observations are likely to be made at precisely 00:00:00 UT.
