Nighttime events

Discussed in #10

^{Originally posted by jamesdeluk May 24, 2023}
Is it possible to create the opposite function, i.e. calendar entries showing night?

Feature request: Allow for notifications

It's nice to be able to see sunrise and sunset times, but it would be great if we had the option to add a notification e.g. at 0 minutes to sunset, or 30 minutes before sunset. (I use Tasker to read calendar notifications out loud.)

Localization

I'm really glad I came across your project and I really appreciate your work.
I wanted to ask if it would be possible to localize the title of the calendar event i.e. sunrise/sunset?
It's not many words, so it shouldn't take much time.
This could be done either manually or more elegantly with a query parameter?

Caching problem in Thunderbird

I noticed that when subscribing to Daylight Calendar in Thunderbird, offline support must be disabled in the calendar properties (see: https://support.mozilla.org/en-US/kb/changing-calendar-preferences).
Otherwise, a new event is created every time the calendar is synchronized, resulting in a very cluttered calendar view.
This doesn't happen with other calendars I subscribed to even with offline support enabled for them.
So I assume that this is a server-side problem with Daylight Calendar?

Open Source License

You wrote on your blog that you invite others to copy and customize the code.
Can you please put a LICENSE file into the repository, so that this is also visible here.
(e.g. an MIT license would be simple and fine; or consult https://choosealicense.com/)

Relative events

Thank you for this great calendar

Is it possible to set up an event with respect to another? Let say set up something every day 1 hour after sunrise?

Something's jacked up

This calendar was working great until about 2/10/23. Now, it doesn't show any "events" and when I look at the URL in debug mode, the dates are pretty messed up. What's going on?

is there an option for the true noon event?

There are the following events stated in the description:

actual
civil
nautical
astronomical
all

Any way to display the true noon?

Bug in GMT data?

Hey, first of all love this calendar feature! This was exactly what I was looking for.

Then to the bug(?):
I had some trouble getting the correct sunlight times. I live in GMT +1 (Amsterdam), but when I filled in 1 or +1 the wrong sunlight showed up in my calendar (the blue ones in the screenshot).
The sunlight window was correct when I used:
https://gearside.com/calendars/daylight.php?lat=52.4&lng=4.9&gmt=-4
(Orange in the screenshot)

Only the solar noon time seems still off. Should be around 1 or 2 PM.
Is this a bug or did I maybe not use the correct query parameters?

Feature Request

This is not really an "issue", but I was wondering if it would be possible for you to make a minor modification so that instead of showing one single event all day, the url pointed to a calendar with two separate short "events", one for sunrise (or the start of civil daylight, or nautical daylight, etc.) and one for sunset (civil sunset, nautical sunset...). Currently the calendar produces one long event which "squishes" all other events on the calendar; it would be nice to just see sunrise and sunset as distinct events during the day. Thanks so much for making this calendar available!

CREATED time and RRULE (frequency)

When I used it to export for 2021 year for my location, I noticed the ICS actually repeats for 3 years and has a created time from 2020.
Would it make sense to make the the frequency a parameter as well or just eliminate it? Because if I export for a specific year, I likely only want it for that year.
Not sure if the created time of 2020 matters at all.

Integrate average temperatures into events

I always thought it'd be cool to add average temperatures for locations for each daylight event.

what to do with GMT offset during DST?

Without diving into the code, I'm curious do the times adjust for Daylight Saving Time? I'm wondering what to put for the GMT offset, or even why it's required given the lat/lng
