This is calconv, a program to convert between various calendars. It's my first real program, started in order to teach myself Python when I had downtime during the 2020 Covid-19 pandemic.
REQUIREMENTS
calconv is written mostly in Python 3, and uses Fortran for some of the more intense number crunching. It uses NumPy's f2py module to all Python scripts to interface with Fortran binaries, and the Tkinter toolkit to generate the GUI. Due to issues with f2py, I can't guarantee that calconv will run properly on Microsoft Windows.
The specific programs you will need to compile and run calconv are:
- A Python 3 interpreter. This comes as standard with Linux, BSD, and I believe Mac.
- The NumPy library. The Anaconda Python distribution comes with NumPy built in.
- The Tkinter library
- A Fortran compiler. The standard Fortran compiler on Unix-like operating systems is gfortran; on Windows, ifort is more common, but my Fortran makes use of features which ifort might not include
All these components should be available through your package manager (called an "app store" on Mac and Windows). If you do not wish to use a graphical program to install everything, you can enter the following commands on the command line in Linux:
Arch (Chakra, Manjaro):
$ sudo pacman -Syu python tk python-numpy gcc-fortran
Debian (Ubuntu, Mint):
$ sudo apt-get install python3 python3-tk python3-numpy gfortran
Fedora (CentOS, Red Hat Enterprise Linux, PCLinuxOS):
$ sudo dnf install python3 python3-tk python3-numpy gcc-gfortran
MS Windows users can download the components from the following links:
- Python (including NumPy and Tk): https://www.anaconda.com/products/individual
- gfortran: http://www.equation.com/servlet/equation.cmd?fa=fortran
COMPILING
Before you can run calconv, you will need to compile the Fortran code. In the command line, navigate to the folder where you unpacked the source code (which should be the one containing this Readme file) and type the following:
f2py -c julian.f90 gregorian.f90 astro_common.f90 stellar.f90 planetary.f90 solar.f90 lunar.f90 lunisolar.f90 lunistellar.f90 solistellar.f90 stellaplanetary.f90 tides.f90 -m astro
f2py -c hebrew.f90 -m hebrew
f2py -c tibetan.f90 -m tibetan
(This only needs to be done once; however, if Python is updated to a new version number, it can break compatibility with binary code, and so a recompile will be necessary)
RUNNING
From the command line, navigate to the folder where you unpacked the program. On BSD, Linus, and Mac, type:
./calconv.py
on MS Windows, the command is:
.\calconv.py
Dates are entered in the indicated text boxes in the order Day, Month, Year; if there is only one text box, input is a simple number. For now, months must be written in full, and entered exactly as listed here, including punctuation and diacritical marks. A later version will replace the text entry fields with selectable dropdown menus. Years before the calendar epoch are entered as negative numbers; so, for example, the year 44 BC would be input as '-44'.

I have listed the months in this order to avoid confusion.)

- Làyuè
To get the leap month in the Chinese lunisolar calendar, precede it with "Rùn", for example "Rùn Zhēngyuè". In the Chinese lunisolar calendar, the leap month can occur anywhere in the year. For this reason, if a leap month is specified in a non-leap year, the algorithm assumes the user means the corresponding regular month; conversely, if an incorrect leap month is specified in a leap year, the algorithm assumes that the user means the actual leap month.

Leap months are indicated by adding " 2" to the end of Wahso (or Tagu in the case of the Arakan calendar). If it's a date in Tagu before solar new year, add an "*" to the year number to indicate that the lunar year has begun but the year number has not yet incremented. The Kayin calendar year begins on 1 Pyatho, and not on solar near year.

- Deuan gâo
- Deuan sip
- Deuan sip nùeng
- Deuan sip sǎawng
- Deuan aai
- Deuan yi
- Deuan sǎam
- Deuan sì
Thai months are a bit weird. Deuan aai means "Month the first", but the year doesn't increment until Songkran, or solar new year, which falls several months afterward. The lunar month containing solar year year is called Deuan hâa in Laos and Central Thailand, Deuan hòk in Keng Tung, and Deuan jèt in Chiang Mai; note that these are the same month and all correspond to the Indian Chaitra, it's just that the month called "Month 5" in Central Thailand is called "Month 6" in Keng Tung and "Month 7" in Chiang Mai.
The leap month always follows the 5th month of lunar year; it is formed by appending " song khan" to the end. Thus, it is called Deuan bpàaet song khan in Central Thailand and Laos, Deuan gào song khan in Keng Tung, and Deuan sip song khan in Chiang Mai.
To specify that a date comes on or after lunar new year but before solar new year, add an '*' to the year to specify that the year number has yet to increment.
