Across the narrow sea

Last we talked about our calendar and how Rome’s second king has just created to extra months to cover the winter. He was apparently happy with that. But meanwhile, in Egypt…

Astronomer’s Day

As much as I like the attention and all the happy thoughts, I do fell obligated to tell you that this day is far less encompassing than my friends think.

The first day of the week

Isn’t it obvious that the last day of the weekend (emphasis on the ‘end’ part of weekend) is the last day of the week? Not so fast!

Pompilian Calendar

Last we met, we talked about the first King of Rome and his new calendar. After his death was addressed a new calendar, and ended the Winter nonsense. They did that by creating two extra months…

Romulan Calendar

This calendar had a period that was unaccounted for the Winter. And It was very unusual to us. One year ended and people had to wait two months until the new year begun!
