Display sunset and sunrise times as all day events from an iCalendar feed in Google Calendar, your phone or elsewhere.
Example calendar URL:
http://sun.is.permanent.ee/?latitude=59.4388618469&longitude=24.7544727325&title=sunrise,sunset,length_civil&label_length_civil=☼&label_sunrise=↑&label_sunset=↓&start=-100&end=365&filename=sunrise.ics
Modify the parameters in the URL according to your needs. You will atleast need to modify latitude and longitude.
Add the above url into your Google Calendar at Other Calendars -> down arrow box thingie -> Add by URL
The latitude of your location, in degrees.
latitude=59.4388618469
The longitude of your location, in degrees.
longitude=24.7544727325
This sets what the calendar events title will be. You can use any of the below variables in any order:
| variable | description |
|---|---|
| astronomical_twilight_begin | Start of astronomical twilight |
| nautical_twilight_begin | Start of nautical twilight |
| civil_twilight_begin | Start of civil twilight |
| sunrise | Sunrise |
| transit | Noon |
| sunset | Sunset |
| civil_twilight_end | End of civil twilight |
| nautical_twilight_end | End of nautical twilight |
| astronomical_twilight_end | End of astronomical twilight |
| length | Day length from Sunrise until Sunset |
| length_civil | Day length for civil twilight |
| length_nautical | Day length for nautical twilight |
| length_astronomical | Day length for astronomical twilight |
title=sunrise,sunset,length,length_civil
Normally the values of the variables in the calendar event titles are not prefixed with any text to conserve space, but you can change that by adding an URL parameter with the variable name prefixed with 'label_'.
label_astronomical_twilight_end=End%20of%20twilight
What day to start the calendar on from today.
start=-100
What day to end the calendar on from today.
end=365
This is the filename of the file offered for download when you access the calendar URL directly. This needs to be the last URL parameter, because otherwise Google Calendar will not read anything from this URL and will silently fail.
filename=sunrise.ics
