A question for a project where I am working on.
When I was born as an individual on july the first 1983 at 01h, 01min, 01sec PM. how long in seconds do I walk on the face of the earth at a given moment ‘now‘; for example june the second, 01h, 01min, 01sec PM?
What is the best definition to use for a year (Julian, Tropical, Anomalistic)?
Or if the length of a year is changing over time, how to apply these astronomical algorithms ( http://www.geoastro.de/elevaz/basics/meeus.htm ) if your born in 1983?
