I love information like this, and I love to see it manifested in the real world, right above my head.
Dundee is just about on the same latitude as Perth ((The only adjustments needed to make this accurate for Perth would be to add a couple of minutes to all the times to accommodate for Perth’s more westerly longitude.)), so this table is good enough for me. Check it out, and have a look at the data for where you live at various months.
Today (as this is posted) in Perth, we will have 17 hours, 44 minutes and 36 seconds of day time. And for all of June, the sky will never be dark (at its darkest, we will be in nautical twilight).
It’s a fascinating time of year.
