| So if the new moon is listed as being on May 10th, does that mean that the moon that rises on May 10th is the new moon? Or the moon that sets is the new moon?
I get confused when interpreting lunar calendars since the moon often rises one day, and sets the day after.

| Ok, the new moon was a bad example because it rises and sets the same day. The full moon this month is the 24th, and the moon rise is listed as 8:26 p.m. and moon set is 5:10 a.m.. So which one is the new moon? |

| Pretty sure its neither. Those are just the times it rises and sets. New is the instant when the Moon and the Sun have the same ecliptical longitude. Full is 180 degrees apart.
New Moon on 9 May 2013 at 7:30 p.m. Central Daylight Time.
Full Moon on 24 May 2013 at 11:26 p.m. Central Daylight Time.

Yeah with this site you can never be sure, lol. I poked around for a bit before asking, but never found the definition of new and full moon you gave. All I could find were times for moonrise, moonset, new/full moon, and I couldn't figure out how the times fit together. When it I read your response it sorta just clicked. |

According to this website it is neither. New/full moon happens at a specific exact time.

Location: Hayward, Wisconsin | Did I miss something? The "New" moon is when the moon is least visible (after having "waned" itself to near total darkness. At the exact moment listed for the "New" moon (depending on location), the moon begins "waxing" (becoming more visible and putting out more light) until it becomes "Full". The exact time is not really that critical, it is the 2 to 3 day period around the occurrence that many believe in.
Moon up and Moon down is a completely different thing and occurs almost every day. |

| There are 4 important moon phases every 24 hours. The exact times depend on where you are, i.e., yer lat/long. Shep tuned me into this and I bought the same wristwatch he uses. That watch allows you to enter a future date and it will calculate the times for that 24 hour period. Amazing. Look for it at BPS. |

Location: WI | There are good Solunar Apps for smart phones also. The one I have shows everything, and you can look up moon times from years ago even! Nice to look up big fish you caught 5 years ago to see if it was during a major/minor event. |

Location: Kansas City BBQ Capitol of the world | I picked up the My-Cast app. by Garmen and it has a nice iterface where you can see Moon over, under, rise and set as well as Sun, barometer, winds and a host of other information. The app. Makes it simple as you can scroll through the day or week and see where everything is.

| If you know the moonrise and moonset times can you spilt the difference to find the overhead and underfoot times? For example, if the moon rises at 6:00 am and sets at 6:00 pm, would the moon over time be noon? |

For example, if the moon rises at 6:00 am and sets at 6:00 pm, would the moon over time be noon? . Not quite. Orbits are elliptical, and the whole solar system is in constant motion. But you'd definitely be in the ballpark. Can't imagine it would make a difference either way. Looking today you'd be off fourteen minutes. |
