Calculate Local Mean Time (LMT)



Formula

The formula to calculate the Local Mean Time (LMT) is:

\[ \text{LMT} = \text{GMT} + \text{ZD} \]

What is Local Mean Time (LMT)?

Local Mean Time (LMT) is the time at a specific location, calculated by adding the zone description (ZD) to the Greenwich Mean Time (GMT). It accounts for the time difference between the location and the prime meridian (0° longitude).

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ \text{LMT} = 12:00 + 3 = 15:00 \]

The Local Mean Time (LMT) is 15:00.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ \text{LMT} = 18:00 - 5 = 13:00 \]

The Local Mean Time (LMT) is 13:00.
