Here, you can download astronomical calendars for selected cities. These calendars show the length of day, twilight and night, rising and setting times of Mercury and Venus, culmination of Mars, Jupiter, Saturn, Uranus and Neptune, moonlight and much more. For more details see the section "Manuals". Calendars in some locations, such as Norway, include only daylight, twilight and night data. The colours are optimised for printing and also for the PC monitor. Colours on the printed calendar are darker than those that you can see on the display. The calendars are non-transferable. This means that if you live, for example, in Prague and in Sofia, you will need two calendars. Print on A3 paper and laminate.

Note: Planets Mercury, Venus, Mars, Jupiter and Saturn are observable also during the day. Telescope with a mount and filters are needed. Venus is observable also with a naked eye.
