The circular calendar visualizes the possible hours of sunshine at latitude 50 degrees north of the equator for 2020 with the yellow area inside. Two additional thin rings (solid and dashed) mark the sunshine hours of the 40th and 30th latitude north of the equator.
By a concentric hourly scale, the possible hours of sunshine for the days in 2020 can be read. All around, the calendar displays all months and days for 2020, but also the calendar weeks, moon phases and summer, winter, spring and autumn solstices are displayed. It also offers enough space for daily notes.
Honored with the “international gregor calendar award” in silver and the japan calendar award in bronze.
