Calendar Magic is an easy-to-use program that is entertaining, informative, educational and of equal applicability in the home and in the office. Calendar Magic has been tested on Windows 10, 8, 7, Vista, XP, Me, 98 and 95, and has been reported to run without problems on other versions of Windows.
The main features of Calendar Magic are given below (a translation to Polish by Abdul Sattar may be found here and one into Belarussian by Vicky Rotarova here).
- Full year and individual month Gregorian, Afghan, Armenian, Baha'i, Balinese Pawukon (full year only), Balinese Saka, Bangla, Chinese, Coptic, Egyptian, Ethiopic, French Revolutionary, Hebrew, Hindu Lunisolar (3 variants), Hindu Solar, Indian National, Islamic Arithmetical (8 variants), Javanese Pawukon/Pasaran, Julian, Revised Julian, Parsi Fasli, Parsi Kadmi, Parsi Shenshai, Persian (2 variants), Sikh Nanakshahi and Vietnamese calendars. A user option is provided to choose between displaying/printing calendars showing each week starting on a Monday (in line with the ISO 8601 international standard), on a Sunday for North American users, or on a Saturday for Middle East users.
- Various types of planning calendars.
- “Dual Calendars” – full year calendars in various calendar systems which show, not only the months and days for a year in any one of the calendar systems, but also the corresponding Gregorian dates.
- A month-by-month, side-by-side comparison of any two of the 26 calendar systems listed above. The display remains synchronised as you change day, month and year values in either calendar system being viewed. Again, users may choose between displaying each month with weeks starting on a Saturday, Sunday or Monday.
- A "Calendar Collector" – how long will it take to collect all 14 possible Gregorian Calendars?
- Date conversions among the 26 calendar systems listed above, plus conversions to Aztec Tonalpohualli, Aztec Xiuhpohualli, Balinese Pawukon, Thai solar, old Hindu Solar, old Hindu Lunisolar and Mayan date formats. Julian day value, day of week and day of year information is also displayed. For Gregorian dates, many other facts are displayed, such as modified Julian day value, Lilian day value and Rata Die day value, and year related information including Roman numeral form, Dominical Letter(s), Dionysian Period, Julian Period, Golden Number, Solar Number, Roman Indiction and Epact. Various special days are also recognised (e.g. Halloween), as are modern Olympic years, Commonwealth Games years, European Athletics Championship years, and World Athletic Championship years.

Date Detective command button to tabulate the weekday on which a specified Gregorian date d/m occurs for each of the years in the specified range y1 to y2.
In Which Months? command button to list, over a range of years, the months in which a specified day of the month falls on a specified weekday.
- The ability to create, display, update and delete reminders for events (birthdays, anniversaries, meetings etc.) for
next year or
every year. When Calendar Magic is started up, both visual and audible warnings are given for imminent events (those occurring within the next seven days) for which reminders have been set. In addition, a calendar for any month, in this year or next year, may be displayed with day numbers highlighted in red for those days in the month for which reminders have been set. Left-clicking on any
red day will cause the reminder(s) set for that day to be listed.
Out-of-date reminders are also automatically purged by Calendar Magic and appended to a text file, purged.dat, for later reference, if needed.
- A multi-sheet
Quick Notes facility for holding miscellaneous plain text items.
- An alarm clock facility for defining an alarm for a given time on a given date. A user may specify the duration of the alarm which may be repeated, after a specified
quiet time, up to five more times. A separate “stopwatch” function is also provided.
- A “countdown timer” for counting down, second by second, any specified time period to zero.
- “What Time is it in?” to calculate the current time and date for a world-wide location and to identify Time Zone abbreviations.
- “World Clocks” to display simultaneously the local times at any 12 world-wide locations.
- Conversion between normal and French Revolutionary time.
