I have been working on a project which makes the way of calendar calculating by fingers more simple and easier ever since the mid 2009. The result led us to the calculation way for elapsed days by the repetition of division algorithm from the beginning to the end or for the day of the week.

Alias: “The Method to calculate by Zeller formation with fingers in three seconds” Please note, however, that the required amount of memory is quite large. Furthermore, as there are many different points from the finger calendars we introduced in the tutorial and others and it may confuse you, we cannot recommend it. However, because this is the ultimate form in a certain sense, please challenge it if you have a strong desire.

I have skipped several steps mentioned in the “Standard" to reduce burden on memory. The number of counting increases as a result and the speed goes down.

Personally, I like this one the best. When I practiced using it, it seemed that I could reduce the time needed to answer by at least about four seconds. By the way, when the order of the steps is changed, it becomes the method that is used in the demo video on the home page. I feel that it is better to calculate the month before the year, so that is how the present method came into being. This idea is reflected in the other methods (especially high-speed methods).

Final advanced form of finger calendar. The content is substantially the same as “Mutant (tentative)”. You can figure out the day with 6 counts.
