Dates / days / times?

Sorry if this is a daft question, but I can’t find a relevant page on the wiki. How do dates, times, days of the week etc work in Empire? Do we have days of the week and months, and what are their names?

Imperial is phys-repped by English.
As are the day and month names.
The only awkward bit is the year, which is out of sync.

But IC, the Equinoxes and Solstices fall at the same times as they do IRL (as far as I can tell) - so the Winter Solstice is a bit before the New Year (unlike at Maelstrom, where the year changed on the Solstice night itself - which led to some confusion in the first few Empire events…).
