This MMBASIC program (moon_phases.bas) can be used to determine the calendar date and UTC time of the phases of the Moon. It runs on the MicroMite eXtreme, Raspberry Pi and DOS versions of MMBASIC.

Here's a typical user interaction with the software and the results computed by the code.

phases of the Moon
==================

please input the calendar month (1 = January, 2 = February, etc.)
? 8

please input the calendar year (include all digits)
? 2017

new Moon
--------

calendar date August 21 2017

UTC time 18 hours 30 minutes 58.23 seconds

first quarter
-------------

calendar date August 29 2017

UTC time 8 hours 14 minutes 5.30 seconds

full Moon
---------

calendar date September 6 2017

UTC time 7 hours 3 minutes 49.89 seconds

last quarter
------------

calendar date September 13 2017

UTC time 6 hours 25 minutes 54.25 seconds

Here's the link to a zipped archive containing the MMBASIC source code.

That is a lot of code David. I hope that you are putting these up on @CaptainBoing's website because I am sure that they will be useful in the future - if only I can find them.

I'm posting all the MMBASIC code I develop at my Google Drive site which is

MMBASIC by D Eagle

This is easier for me since I often forget to post at other sites like @CaptainBoing and Rob's Circuit Gizmos. I've got a good memory, it's just short!

There is also gfortran code for the Raspberry Pi at

Hi David,

did you have a program that calculates the moonphase for a specific date/time?

THANKS!

I do but have not ported it from QuickBASIC to MMBASIC yet.

Item #73 on the list of things I want/need/should/could do.

So many lines of source code, but only 23 hours and ~56 minutes in the sidereal day.

Ok, I can wait!
