There's an idea for a math assignment including MediaWiki internal variables, and a bit of astronomy. It is understood that the student will have to write a template related to the calculation of time intervals limited by computing means MediaWiki. Does such a task fall into the competition theme?

@Carn Hi, hard to say without more information. :) Would working on this take a complete newcomer about 2-3 days to complete? I'm not sure what "time intervals limited by computing means MediaWiki" is supposed to mean.
It means using {{#time: }} {{#expr: }}and other en:Help:Conditional expressions to calculate a specific date associated with the movement of the Earth around the Sun and the Moon around the Earth, knowing some initial values. What is the deadline for preparing the assignment?
@Carn You can create tasks on the Google Code-in site at any time, see https://www.mediawiki.org/wiki/Google_Code-in/Mentors. GCI runs until 2020-01-23.
