absence

Absence is an efficient calendar tool that helps you keep track of people or objects on a daily basis. Built with Perl, it can be easily adapted to suit your needs. One of its primary purposes is to replace the ubiquitous whiteboard that is commonly found in office spaces. You know the one - with its permanent magic marker and non-permanent markers used to indicate vacations, training, and other events.

With absence, you get a CGI system that provides a resolution of one day. It may not be suitable for recording appointments or other activities that require a finer resolution, but it's perfect for keeping track of important dates and events.

The absence system generates an image for each month using the GD library, which can be customized to produce PNG, GIF, or even JPEG formats. This feature allows you to display the calendar images on your website or in any other medium of your choice.

Overall, absence is an excellent calendar tool that simplifies the process of keeping track of important dates and events. Its ease of use and flexibility make it a great choice for anyone who needs an efficient calendar system.
