MOON
CALC.
Can you look at the moon and tell if it is waxing or waning, whether the tides are getting stronger or weaker, or what time high tide is?
​
With the Moon Calculator, you can! Simply spin the wheel so the moon's face shows at the top and you can see the tide times and intensity, in addition to the time of moonrise and moonset - essential knowledge for nocturnal adventures.
CHOOSE
YOUR EDITION
We offer three editions for you to choose from. The first option is the 'Universal' which you one up the tide times with codes for locations (see below). If you want a calculator with the timings set for a specific location, you can can select a 'pre-made' edition of popular locations or commission a 'First Edition', custom-made for you, for anywhere in the world.
FINDING
YOUR CODE
​For the Universal Edition you can find the times of High Tide for multiple locations, simply by reading off the time next to their code. Here's how you find the code for a specific location.
1) Find the time of high tide for that place on the Full Moon
​
2) Set the calculator to Full Moon and see the code closest to that time; this is the code.
​
3) To save you having to remember codes, there is space on the calculator to write the codes of three locations.
