Are you planning to learn any invaluable skills this year?

Yesterday, I paused the animation of inner planet orbit to record the dates of

**interior conjunction**of the sun, Venus, and Earth: August 15, 2015; March 26, 2017; October 22, 2018; June 13, 2020; and January 11, 2022. I noticed that Earth travels about a lap and a half in between each conjunction. The screenshot shows what I mean by interior conjunction (the sun, Venus, and Earth on the same line).

If you are a person who finds yourself “yet to know math,” ignore the fraction-decimal talk for now. Perhaps, that is a captain idea we can explore one day.

The pie chart makes me wonder where the point of conjunctions falls in the Earth's orbit, which I decided to label the orbits with the calculated date since my observed dates might be a little off. Using spreadsheets — number one on the list of 24 — becomes invaluable at the point.

How many days are there between each conjunction?

I multiplied 1.6 years by the number of days in a year (365.256) to get 584.41 days. Here is why spreadsheets are great if you dislike tedious calculations as much as I do. I can put the start date (1/11/2014) into a cell of the spreadsheet. In another cell, I can add 584.41 to the date and it tells me the new date. Then, I can copy that formula in the other cell to calculate all five conjunctions. Poof! Just like that! The spoilers page shows you my work.

**Spreadsheets let you play with math without having to do the calculations!**P.S.S. 27 days and a wake-up until the winner of the potholder giveaway is announced. So, far, I have three names on the qualifying. What giveaway? Read on for more details.
