DownloadThis calendar seeks to present what most Western sources would consider the official data for each day between 500 BC and 2238 AD. The underlying research takes account of technical and historical issues.
The download is available through the Files tab (above). The download includes PDF and Microsoft Excel versions of the calendar. The PDF is a 10,000-page file, bookmarked by century. The Excel version states Julian calendar, Julian day, (proleptic) Gregorian calendar, day of week, and ISO 8601 values for each of the 1,000,000 days covered, one day per row. (Click on screenshot, below.) A separate tab in the spreadsheet states Julian days extending back from 500 BC to 4713 BC.
The Support tab (above) links to a blog post detailing the factors considered. Please post questions and comments on the Discussion tab (above). The spreadsheet is, of course, modifiable to suit specific purposes.
