Rosh Hashanah is the first day of the new year. We have just entered, by Jewish reckoning, the year 5769. I have seen it written in some scholarly works as 5769 A.M., from the Latin anno mundi, meaning the year of the world, i.e. of the creation of the world.
In the Rosh Hashanah liturgy (the holy day has its own thick prayerbook) we say to God:
"This is the day of the beginning of Your creation, a memorial of the first day ... today is the conception of the world."
I took the photo now of a postcard I carried around the world for several years. It is a painting by the wonderful artist Sieger Köder called "Schöpfung" [Creation], Und Gott sah alles an, was er gemacht hatte, und es war sehr gut" (from Genesis 1).
