Download Calcium
Download and install the Calcium demo package to try it on your own server. It's fully functional, but limited to 1 calendar. The demo version will also display links to our web site above the calendar.
Please read the brief license agreement.
All installation methods create only two things: the file 'Calcium40.pl' and a directory called 'CalciumDir40', containing the rest of the required files. Nothing else on your system will be affected.

Install using an OS-specific installer

If you're installing on your own server, try one of these:

for Apple OS X: Calcium404.pkg.zip
for Microsoft Windows: Calcium404.exe

After installation, just browse to the Calcium40.pl script to start using Calcium.
For example: http://your.domain.name/cgi-bin/Calcium40.pl

Other Installation Options

If you can't use an installation executable - typically the case if your web site is on a remotely hosted system - you can instead:

  • use the CalciumInstaller.pl CGI installation script
  • or just download and unpackage a .tar.gz, .tar.Z, or .zip file
CalciumInstaller.pl CGI script

'CalciumInstaller.pl' is a small CGI script you can use to easily install the full package. Just download it, put it in your web server's cgi-bin directory (or equivalent), and browse to it - it will display simple instructions. If Perl on your server is "web-enabled", it will retrieve the full installation package from our web site and automatically install it.

Download the installation script: CalciumInstaller.pl
(< 10K bytes;  Right click the link, and pick "Save Link As..." or "Save Target As...")

Zip or tar package

Or, download one of these packages and extract it in your web server's cgi-bin directory. That's pretty much it! Works with any system. All packages are < 1 megabyte

Calcium4_0_4.zip ZIP file; Microsoft Windows, Unix/Linux, OS X
Calcium4_0_4.tar.gz gzip-ed tar file; Unix/Linux, OS X

Note: If you can't unzip/untar the package directly on the web server, you can extract the files on your desktop computer and then copy everything up to the web server. Be sure to preserve the directory structure if you do this.


Notes:
  • If you need a different format or have questions, please send us email.
  • You can peruse the on-line documentation at your leisure, including some installation tips and a list of installed files.
  • Instead of downloading and installing it yourself, you can try your own private installation of Calcium on our servers! Nothing to install, ready in 1 minute - get started now.
  • If you see the program text displayed when you browse to the calendar, try renaming the script with a '.cgi'extension, instead of '.pl'. (The script can actually be named anything you like; the extension is needed on some web servers (e.g. IIS) to identify how to run the script.)
  • File Permissions: make sure permissions are set so the web server can:
    • read everything
    • execute the main 'Calcium40.pl' script
    • write to the 'CalciumDir40/data' directory, and all its sub-directories
  • All Calcium files are plain ASCII text. If you use FTP to transfer Calcium files between machines running different operating systems (e.g. Windows and Unix), make sure you do so in "ASCII mode".
  • Apache users: If your Perl executable is not in /usr/bin, you'll likely need to edit the very first line of the main script (Calcium40.pl) to reflect the actual path to Perl. (For Apache users on Microsoft Windows, that's normally c:\perl\bin\perl)
  • Apple OS X: Here's a page with some simple installation instructions.
