What "day" of the moon is it?

[MartinHiggins]

Hi All,

Just wanted to check on how to calculate what the "day" of the moon  is. Using this site:

Moon Phases Calendar | Moonphases.co.uk

Would I be correct to assume that day 1 is the day after the indicated new moon, i.e. 15 November and therefore  today 28 November is day 14?

Cheers

Yes:

Quote

For most dates in the above Moon Phase Calendar, there is listed at the bottom of the grid cell a number of days, such as “18 days.” This tells us the amount of days since the previous new Moon, or in other words, how many days into the lunar cycle we are—aka, the Moon's age. So, at the new Moon, that day is “0” (not labeled); the next day, 1 day has passed; and onward until 29 days pass and we are at the next new Moon.

 

From here. Almanacs often use this kind of numbering.

Thanks Waddensky!
