Date Wheel with Reverse Printing

Both the logo and the markings are printed at the same time and a Pantone colour match is okay as are half-tones.  For an additional visual effect, one might consider printing in a reverse colour as is shown on the Hooper Welding Enterprises Ltd. wheel calculators shown above.  The artwork does not have to be very complicated.  Don’t worry about getting the scales right. All we need is the art for the inside of the wheel and it is just dropped onto the template.  For coloured wheels with an image, be sure that the image is at least 300 DPI else it will not reproduce well and be clear and crisp.

The date wheels come in two different sizes.   4 1/4″ and 6″ diameter sizes.  They can be printed in 1 colour or multi-colour.   The single-colour calculators have a glossy finish and the coloured wheels have a matte finish.  On the coloured wheels, you may also print on the reverse side in colour.  White is not considered a colour. The calculator is shown above, for Bristol-Myers Squibb uses half-tones for a 3-dimensional effect.

About Date Wheel Calculators

Date wheels help users calculate a date some number of days before or after a given date. It’s particularly useful in industries where precise scheduling or date calculations are required, such as project management, manufacturing, or event planning.

How it works

This is typically a circular disc with dates printed around its perimeter. There’s an inner disc that rotates within the larger outer disc. To use it, you align a specific date on the inner disc with the “0” or “today” marker on the outer disc. Then, you can see the resulting date after adding or subtracting a certain number of days by looking at the corresponding number on the outer disc.

What is a calendar wheel?

A “calendar wheel” or “date wheel” is a tool that allows users to calculate specific dates by adding or subtracting a set number of days from a given date. This is particularly useful for professionals in industries where accurate scheduling or date computations are important.

Is a physical or online version better?

Online date calculators are great, but physical wheels are easy to use, always available, there is no technology dependency, better for your eyesight, fast, and durable. They are also great learning tools for kids and young adults.

How do date wheels account for leap years?

Leap years add an extra day to February. Some wheels might have corrections for leap years, while others might not. Users may need to make manual adjustments when calculating dates around February in a leap year or ensure they’re using a date wheel designed to consider leap years.

Can a date wheel calculate business days instead of calendar days?

Standard date wheels typically show calendar days. However, for professionals who are concerned with business timelines (which exclude weekends and sometimes holidays), this is a crucial question. There are specialized date wheels and digital tools available that can help calculate business days specifically.
