The Ra Calendar 
I suggest we introduce a new calendar.
Frankly, the presentday Gregorian calendar is doing its job rather badly.
Firstly, all months are different. One month might go on for 31 days,
the next for 30 or perhaps 28 or even sometimes 29.
This schedule is quite ridiculous. The present mess starts far back in our (western) civilisation. The calendar we use today was introduced in 1582  with the intention to repair the faults of the even older Julian calendar  since the B.C. calendar was going crazy with the New Year's Days.
So there we have two things to repair:
each month must be made to have the same length, say 30 days.
And the turn of the year must be fixed 
say at the return of the sun light (or as an alternative: when at its peek).

The Ra Calendar is very simple, repeating itself each quarter.
Each quarter ends with an extra day 'X', that marks one of the four
Solistice Days.
At year's end another one or two extra days are added to the counting: The Year Day is marked 'Y' , and occurs each year. The 'Z'ero day marks the Leap Year Day. All together, this sums up to the about 365.25 days of a year. I have made a computer program for the Ra Calandar. It shows the days, weeks, months, quarters and years like an ordinary calendar. But they are shown in a new counting. The present date of our presently used Gregorian calendar is translated into the countings of the new calendar. 
THE NEXT STEP
One step further would be to simplify the week even more..
that is to make one week 10 days.
To keep work/leisure hours intact there would have to be three days off every week. 3 days out of 10 is 30% off (to compare with 2 days off in a 7day week, i.e 28,6%).
AND.. why not change the dygn (day&nightcycle) to 10 hours! This is what can be seen in pictures below..
There are four solistice days per year (SOL14). Below is the midsumer day ..
The picture above shows the new weakly 10days x 10hours time cycle
(left with big clockdial),
and the old 7days24hours time cycle (right, small clockdial).
To explicitely give the datetime numbers ..
NEW SOL= 2018.06235.39.32 [YEAR.MMDDH.MI.SE]
is the same as
OLD GRE= 20180623 12:56:36
Take some time to study the data conveyed in the pictures.
As you might find out the small conventional 24hour clockdial
has the added information of sunrise (red) and sunset (brown);
this information is more visible on the 10hour dial though.
The two pictures above depict the Midsumer day at two different latitudes..
 to the left at the Geneva Latitude, with 15,36 light hours.
 to the right at the Stockholm Latitude, with 18,17 light hours.
On can compare the light and dark hours on the bigger 10hourdygn clockdial.
Also, try to figure out how many seconds there are in day say,
with the new and old time counting
 supposing there are 100 newseconds in a newhour.
