Jan 1 is a entirely arbitrary demarcation that's not actually terribly useful to the way we actually experience time and the year. IMO a better place would be one of the solstices or equinoxes (I'm partial to the spring equinox).
Also breaking the year into quarters, from equinox to solstice would be a better match for to scale we live an think on. Also it's just the right amount of time for a good portion of a large one-man project.
It's only the spring equinox on your half of the planet! You'd have to call it the March equinox which is arbitrary again. Or maybe the Northward equinox.
