Introduction

Use this Perl class to create a monthly calendar. It's easy to use and highly customizable, supports multiple languages, and you can choose whether weeks start with Saturday, Sunday, Monday, or any other day. Of course you can create as many calendars as you like. Have a look at the example below. It shows five calendars; the current month (big in the middle) plus the two previous months (left) and the two next months (right):

In 1582, Gregory XIII made a calendar reformation (advanced leap year rules + 10 days have been dropped in October) and created the Gregorian calendar, which is in use since then. Therefore HTML-Calendar applies the Gregorian calendar for years > 1582, and the old Julian calendar for years <= 1582.

Regarding week numbers, HTML-Calendar applies the following rules:
  • One week consists of 7 days.
  • The first week of a year must contain at least 4 days, or else it will appear as last week of the previous year. This may vary depending on the day that starts the week (Saturday, Sunday, Monday...).

Important notes for users of older HTML-Calendar versions

In version 2.7, two variables were removed: tdFontColor and tdBGColor. They were replaced by a new variable tdBorderColor. This has been done because the current day (today) is now just marked by a border, leaving font color and background color unchanged.

Be sure to update any scripts that use HTML-Calendar accordingly. Sorry for the inconvenience.
