We in UK are about 2 weeks away from a celebration, thats a bit like 4th July in America, we also use fireworks on 5th November, but before i show research, i must show you why i have to add 10 days to 5th November 1605 in London and the Gunpowder Plot, link below:-

There is poetry to this event below:-
Remember, remember the 5th of November,
the Gunpowder treason and plot,
There is no reason, why gunpowder treason,
should ever be forgot!
To apply archaeoastronomy to 5th November 1605 in London, you need to know how most astronomy programmes work, the Catholic reform called the Gregorian Calendar happened in 1582, but a protestant country like UK continued to use the Julian Calendar till 1752, in 1605 that means that there is a ten day difference that must be added to 5th November to get it in synch with any astronomy programme.
Astronomy programmes won't do that for you, mainly because although we are sure when England and American Colonies changed calendars, there are some areas of Europe that are unclear, so astronomy programmes generally only show the Gregorian Reform Calendar of 1582, and leave it up to you to adjust, in England in 1605 i'm very sure i have to add ten days, but in some areas of Europe, it becomes a nightmare to get it right, an example would be link below regarding the very important religious wars played out in what we now call Germany, and the protestant reformation started by Martin Luther, who died in 1546.
Anyone interested in Archaeoastronomy would be interested in "The 30 Years War", however because of conquest going one way or another and the calendar constantly changing from Julian and Gregorian, i can't have much of a comment other than to say i'm confused ha ha!

This doesn't apply to Gunpowder Plot, i'm sure i have to add ten days to my astronomy programme, so to get it in synch, it won't be 5th November 1605 in London that i will be looking at, but 15th November 1605, i'll start on next thread section,
