Summary
| Description |
English: Duration and distribution of horae and vigiliae on equinoxes and solstices of the year AD 8. The surise and sunset times for this diagram are calculated for Forum Romanum 41°53′33″N 12°29′07″E / 41.892426°N 12.485167°E AD 8 (the Julian calendar). Sunrise and sunset times are used as boundaries of day and night. Many sources however are ambiguous because of confusing terms sunrise with dusk and sunset with dawn. This is important, because times of dusk and dawn differ significantly from times of sunrise and sunset. The parallax and atmospheric refraction are taken into account. Equinoxes and solstices are computed too, not set by Romans. |
