Unclear definition[edit]

"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.[7] Tide tables tell the time of the next high water.[8][9] 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."

But there are three times mentioned. Which two are we supposed to take the difference of? (talk) 10:32, 13 January 2015 (UTC)
