Your program Lunar Calendars and Eclipse Finder is great.

I study ancient near east history to reconcile datable historic
events with Bible passages. This often entails ascertaining the
dates of New Moons, Full Moons, Vernal Equinoxes, Lunar and Solar
eclipses. I have been using Hermetic's Lunar Calendar and Eclipse
Finder (LCEF) and Equinoxes, Solstices and Cross-Quarter Days
(EqSol) products since 2013.
My analysis typically entails using the Fourmilab calendar converter
to convert ancient Hebrew dates into Julian Days, and then input
those Julian Days into LCEF to obtain a confirmation of the Julian
Calendar Date, and then calculate proximate dates for Dark and Full
Moons. I use the Julian calendar year as input into EqSol to obtain
the vernal equinox Julian Calendar date and time, which can then be
pasted directly into LCEF to obtain the Julian Day and phases of the
moon.
As Dark Moons are not visible, LCEF also provides a date
increment/decrement facility which allows me to step by minute or
hour from Dark Moon to some humanly visible phase of a New Moon
crescent, and then readout the corresponding Julian Calendar date
and time.
Both LCEF and EqSol provide a log of conversion results which can be
copied and saved for later referral and checking without having to
rerun the conversions. This greatly helps being able to reconfirm
at a later time how various results were obtained.
Both LCEF and EqSol have always executed without error, and the
results compare closely with tables of Lunar and Solar events
published by NASA, the US Naval Observatory, and Fourmilab, but
further, LCEF and EqSol allow me to compute more details of
additional events not computed by NASA or the USNO.
LCEF and EqSol are indispensable tools that ensure the accuracy of
my research.

Lunar Calendars and Eclipse Finder is a great tool for any calendar researcher interested in exact astronomical data. It offers quick and precise results for all kinds of eclipses on the minute in GMT or local time. Dates are displayed in different calendar systems and it's easy to add and subtract any given number of days for immediate results. Absolutely fabulous ...

The Lunar Calendars and Eclipse Finder software is great for checking historical lunar references such as can be found in religious texts.

I have been running Hermetic's "Lunar calendars" since 2008 with good success. My area of interest relates to biblical dates found in ancient Hebrew texts. Accuracy is essential and this tool has enabled that. Thanks!

I have used this program for many years now. I find it easy to use & invaluable for my purposes. I'm able to create a calender of lunar events for years to come that helps me program my work schedule of lunar celebrations as well as for personal & garden rhythmic cycles. I'm very happy with this software & always take it with me when I upgrade my computer.

— Bob Henstra, August 25, 2012
I can say as a student of history and astronomy that the LCEF and EQSOL programs are a good way to verify the dates of heavenly events. And the price is reasonable, with great customer support! I intend to try other Hermetic products.
— Frederick Young, July 30, 2012
It is astonishing! I'm happy with the capability of this software.
— Pablo Quintana del Carmen, July 29, 2012
I really enjoy this software. I'm gathering an extensive database of historical dates. Many of them rely on the accurate sighting of the new moon for which this program provides a reliable approximation.
— Michael North, April 12, 2012
Since purchasing the program I have found it very useful for checking the Moon's phases, etc. I am also pleased by its ease of use, and the excellent support given by Hermetic Systems.
— Robert Forbes, December 29, 2011
Your products work well and your prices are very good. Thank you.
— Thomas P Cook, August 18, 2011
Without LCEF I could never have learned the secrets of eclipse prediction so reliable and fast, and practically without any higher math. Since LCEF can be used offline, it has all the calendar information readily available, even when I'm traveling. Hermetic's excellent support and response times have made using the product a
pleasure.

Like this program very much. Very helpful for historical research.
— Paul W Puckett, June 18, 2010
It works properly and it is a greal tool for forecasting purposes.
— Pablo Quintana, December 29, 2009
You have helped me tremendously in my research concerning dates in the Mahabharata by doing the new version, as well as by finding out the dates of eclipse pairs that I needed.

My research focuses on the Khmer civilization from Angkorian times to the present. I purchased three Hermetic Systems tools: Easy Date Converter, Lunar Calendars and Chinese Calendrics. Each one is an excellent, well designed, well documented piece of software. They have proven themselves indispensable in my work.
My most recent project is translating the biography of Cambodian dancer, published in French in 1919. Not a single Western calendar date appears in the text. Using the extraordinary Chinese Calendrics program, I was able to pinpoint multiple event dates as the text gives clear descriptions of festivals based on the cycles of the moon and the Chinese zodiac. This small feat enhanced the historical value of the entire text.
In closing I must also praise the excellent technical support provided. The programs are clear and well documented, but I did have a few technical questions. In each case I received a fast, detailed solution.
