How to use the perpetual calendar?

Let's say we want to check what day of the week it is on March 2, 2019. To do this, we turn the calendar to the side of the moon's smiley face. We search for the number 20 on the moving ring and align it with the number 19, which we find on the stationary dial. Next, we move the Letra Dominical lettering to the 19, which allows us to see what letter was under the 20 when the 20 and 19 were aligned . In our case it is the letter F.

The next move is on the sun's smiley face side. The month of March marked on the moving ring with the letters MAR is placed under F. After that, we see that the 2nd day of the month-we are now looking at the lower part of the stationary dial showing the days from 1 to 31, coincides with the letter S, which means that March 2, 2019 is S - Saturday.

In the case of a leap year, it will turn out that we will meet 2 letters in the scepter. Then the rule is that the first one applies to the day up to March 1 of a given year, and the second to any day after March 1 of that year. Other steps as above. Example: let's check what day of the week falls on June 10, 2020. On the moon side, we set 20 of the moving dial under 20 on the stationary one. We use a pinkie and see that there are the letters D,E under 20. We are talking about a date after March 15, so we consider the letter D. With this information we go to the page with the sun's smiley face. JUN - June is set under D. At the bottom we see that the 10th of June is under X- miercoles - Wednesday .
