- MoonCalc provides information relating to the position, age, phase, orientation,
appearance and visibility of the moon for any given date, time and location on earth. It
also provides the time and direction of moonrise and moonset, interval between sunset and
moonset, interval between sunrise and moonrise, date/time of astronomical new moon
(conjunction)and full moon and predicts the likelihood of visualising the young moon from
a particular location. MoonCalc provides Hijri calendar data including location dependent
Hijri date conversion using predicted lunar visibility.
- The program can scan the globe at the start of any lunar month to find the location,
date/time and direction of earliest crescent sighting using a variety of ancient and
modern moon sighting criteria. The program is able to draw world maps (flat and spherical
projections)showing areas of the globe where the young moon is likely to be seen.
Graphical displays showing the position of the moon on a star chart and the position of
the moon in a simulated local sky can be produced and printed out. A close-up of the near
side of the moon (showing orientation of the moon's limbs and position of the lunar
craters), correct for a given observation site, is also provided. This close up takes into
account the effect of libration and 'limb shortening'(optional).
- There is a choice of either topocentric/geocentric co-ordinates and apparent/geometric
sunset. Correction for atmospheric refraction is optional. The program has a built in
atlas database which stores latitude and longitude data of upto 1000 cities (ships with
about 100 cities already entered). There are many user-configurable features.

- MoonCalc was developed over a period of 4 years and continues to be in a
- state of constant development. The program has given me a lot of pleasure
- to write and I hope very much that you enjoy using MoonCalc and find it
- useful.
- Users of MoonCalc are encouraged to test the various functions
- of the program and compare the data produced by the program with actual
- sightings of the moon, particularly sightings of the crescent moon. All
- suggestions and comments which may improve the program are welcomed.
