"The approximate lunitidal interval can be calculated if the moon-rise, moon-set and high tide times are known for a location. In the northern hemisphere, the moon is at its highest point when it is southernmost in the sky. Lunar data are available from printed tables and online. Tide tables tell the time of the next high water. The difference between these two times is the lunitidal interval."
Three times are mentioned: moon-rise, moon-set, high-tide.
"The difference between these two times is the lunitidal interval."
