As I was talking about Jewish rulings:
Rabbi Israel Lipschutz, who lived in Danzig (now known as Gdansk) in Poland in the early 19th century distinguished between places like Copenhagen,
where it may never get really dark out at night, but where the
sun does actually set every day, and places further north where the
sun stays above the horizon for months at a time. He ruled that in places where the sun does set,
Shabbat begins when the sun sets, even if it never gets fully dark, and
even if sunset is well after midnight. Shabbat ends 25 hours later regardless of whether it gets dark enough to count three stars.
But
in places where the sun doesn't set at all, Rabbi Lipschutz ruled
that a traveler should adopt the clock of the place from which he departed. The obvious question, then, is from which he departed when, exactly? From his hometown? From the last village he was in before he entered the all daylight zone?
In places where this ruling was relevant, it seems that communities had the custom not of holding Shabbat based on each individual's port of embarkation,
but based on the nearest significant Jewish community. At the time the practice was first instituted in the 19th century,
that happened to be Hamburg, Germany (one rabbi has suggested that the first community that needed to do this adopted Hamburg time because their rabbi was from Hamburg, and all other communities just followed their lead).
Rabbi Lipschutz's ruling aside, there are some different practices that you may find in these northernmost Jewish communities. I consulted with Daniel Reisel, a Jewish friend of mine in Norway to see what his community does. Apparently the
Norwegian custom in the summer months (based on a teaching from the
Baal Shem Tov that says we are all always walking towards Jerusalem) is to bring in
Shabbat at the same time Shabbat begins in Jerusalem. So if candle-lighting time in Jerusalem is at 7:45pm, Shabbat in Oslo begins at 7:45pm local time. Shabbat ends the next day when the
sun is at its lowest place on the horizon.
During the times of year when the sun does set, some people bring Shabbat in early. (According to Jewish law, you can't begin Shabbat as early as you want. Typically,
the limit is about 90 minutes before sunset.) Others wait to light candles on time, which may be after midnight. Regardless of when you light candles,
Shabbat does not end until the sun has gone down the next day, which can sometimes be very early Sunday morning. Many people do havdalah upon waking up on Sunday morning.
If you choose to go with Rabbi Lipschutz's ruling of going by the
nearest Jewish community, you may find that that candle-lighting time in that city is not until after midnight on Friday night, and Shabbat doesn't end until a few hours into Sunday. So, waiting to have your Shabbat dinner until after candle-lighting time may be a challenge (especially if you have small children).
If you can't or don't want to wait up in order to begin Shabbat on time, you may want to consider having a festive meal with your family on Friday at dinnertime, and simply lighting candles without saying a blessing. Instead of the Shabbat
Kiddush, just say the basic blessing over the wine. You can maintain your traditions, even without staying up until one in the morning. This "Shabbat" dinner is a great time to talk to your family about what it means to observe Shabbat. Do they think of Shabbat as
strictly tied to a time period, an event, a ritual, a community, or do they think of Shabbat as something that is more spiritual and can happen anywhere at any time, even if it isn't Friday, or doesn't get dark?
There are some Muslim communities who follow such rules:
1) Break fast following the time at their homelands (even if their kids are born and raised in Scandinavia and that is their homeland)
2) Use twilight hours (even if it means fasting 20-22 hrs)
3) Some even follow Saudi
4) Follow the nearest Muslim community or the nearest town where the sun does set or atleast hits twilight!
Why so? In Germany today it is 18.5 hrs
In Italy it is close to 17hrs
In UK it is 16 hrs but Scotland it is more
In Helsinki it is 20 + hrs
So why the northern tip gets 16 hrs while the middle of Europe has 16-20 hrs?
I havent seen that video, can you please put the link here?
