The UK will stay the UK as long as the people in the UK want it to.
Its irrelevant what people from elsewhere think, do or support.
And you right us off at your peril my friend, we Brits are at our best when our backs are against the wall and we're fighting the odds.
Do not be fooled.

Unfortunately, I see that we had different teachers and different history textbooks.
This cannot prevent us from finding common ground and agreement.

The thing is the Moon has an extremely thin atmosphere.
And it lacks the necessary conditions to support the formation of clouds as we understand them.
Might be something to do with the shadow cast by the Sun i suppose.
Yes but it seems 360 day and 365 day calendars and years have co-existed for much of that time. There were at least two ways to get them to synchronize so you didn't end up with your winter festivals happening in the summer, as would happen with a strictly 360 day calendar:

Definitely a lot to think about with this one, time keeping is a skill cultures are built around. For every story like this I'd imagine 10 have been lost. Evidence suggests we've had 365 solar days for at least 5-6000 years though?
...the Egyptians, basing the calendar on twelve thirty-day months, intercalate five additional days every year, whereby the cycle of the seasons returns with uniformity."
At the beginning of the new year, an observation of the first “Green ears of barley” was made and it was decided to add or not a 13th intercalary lunar month (Veadar) to the old year.
The DAYS360 function returns the number of days between two dates based on a 360-day year (twelve 30-day months), which is used in some accounting calculations. Use this function to help compute payments if your accounting system is based on twelve 30-day months.
Over millions of years, Earth's rotation has been slowed significantly by tidal acceleration through gravitational interactions with the Moon. Thus angular momentum is slowly transferred to the Moon at a rate proportional to r^−6, where r is the orbital radius of the Moon. This process has gradually increased the length of the day to its current value, and resulted in the Moon being tidally locked with Earth.
This gradual rotational deceleration is empirically documented by estimates of day lengths obtained from observations of tidal rhythmites and stromatolites; a compilation of these measurements[44] found that the length of the day has increased steadily from about 21 hours at 600 Myr ago[45] to the current 24-hour value.
