Monthly Office Calendar tool for Excel

Office Calendar for Excel - Techronology

Overview of the Office Calendar

Originally, the Office Calendar (or OC) was created in Excel 2003. Overall, it is a beautiful tool and easy to use. In addition, it lasts a lifetime.

Once we got a hold of a higher version of Excel, we made the upgrade.

Keep in mind, this is an open source tool. Thus, you are free to change different aspects of the tool, to suit your needs. We will probably mention that a few times.

Enterprise version

We also have an enterprise version of the OC. It allows you to clear all your entries on the calendar, with just one click. That makes working the calendar much easier.

Control panel

OC - Control panel - Techronology

So, the control panel allows you to change settings of the OC. In short, you can select a language, year, month, start day, and color scheme. Also, you have the option to show or hide lines for each day.

Language selector

You have the option of selecting from three languages: English, French, and Spanish.

Over 450 years

Remember, we mentioned this OC lasts a lifetime. You would have to be pretty old to outlive it. In any case, you have the option of selecting from 1900 to 2400.

Month selector

Of course, the month selector is straightforward. You have twelve to choose from.

Start day picker

OC - Sunday start - Techronology

With the start day picker, you can select Monday or Sunday as the first day of the week.

Color scheme selector

Accordingly, you can select from three color schemes: green, blue, or gray. If you are ambitious and want more color, then you can apply your own colors manually.

Show or hide daily lines

Some people prefer to hide daily lines. Therefore, we put in an option to allow you to show or hide these lines.

Calendar miniatures

When we selected December 2400, it actually showed January 2401 as the following month in the calendar miniature. Hence, the OC may last forever.

Using the OC

On the whole, using the OC is pretty easy. Additionally, you are not necessarily stuck with all the features mentioned above. In fact, you have the freedom of making changes as if you are working in any spreadsheet file.

For example, see all the basic entries and formatting we did with the calendar below.

As you see, you can type into any day on the the calendar. For this reason, it is a great tool to enter events, birthdays, and special days.

In the above calendar, see all of the cool stuff we did with the OC. Also, take a look at the notes section.

Again, anything you can do with a spreadsheet file, you can do with the OC.

Basic version

So, we also have a basic version to the Office Calendar. Really, the only main difference is that, the basic version does not have calendar miniatures. However, it has a bigger notes section.

Another difference is, we do not plan to update the basic version. Any updates will occur with the Pro or higher versions.


The OC prints out nice, with one full calendar page. This also means, you can create a nice full year calendar in no time.

Developer’s note

At the time of development of the Office Calendar, we had big plans to really make it a powerful tool. But, we did not put any code into it. For the most part, the OC is built off of custom sheet formulas and a user friendly design.

Although we have ideas on what you can do, we will leave it up to you to decide. It is all open source. So, enjoy!


Make sure you follow us. This way, if we make any changes, then you would be aware of them.


Requirements: Excel 2007 or higher or compatible.
