Hi!

I want to present here library of the calendar functions written by me with FASM.

Functions exported from this DLL library give the programmer some abilities:

• works with dates from the interval of 11 million years:
  
  
  • from 1 Jan 5843880 BCE to 3 Aug 5915100 for the Julian calendar,
    
  • from 30 Dec 5844001 BCE to 17 Jan 5915222 for the Gregorian calendar,
  
  
• convenient conversions between Julian and Gregorian calendars for dates from supported time interval,
  
• calculation of the day of the week for the given date,
  
• calculation of the number of the day in the year,
  
• determining if the given year is leap in chosen calendar,
  
• calculation of the "absolute" day number for the given date (it could be used to calculation of the distance between two dates).
  

Here you can download source of the library (encoded in UTF-8), compiled DLL and description in PDF file.

Project's homepage: http://mikhajduk.houa.org/EN/Calendar.php

Because library was described in 3 language versions here you have also:

• Russian language version,
  
• Polish language version.

I am impressed that you can calculate the leap years and things for such long periods. Not even the experts have been able to predict the leap years so far ahead! See here if you are interested.

nice work man

I liked very much the documentation, have you done it with TeX/LaTeX?

Very nice code, and the documentation I agree is beautifully done! Great work!

Yes, it's written with LaTeX and compiled with pdflatex program.

[clap] A very good example of ... well everything from coding to documentation.
