Instead of a bunch of boring facts -- these events become processes in themselves. Knowing that Columbus left port on August 3rd --- means the PROCESS of discovering America was an ardous task that merely ended on October 12th.
Geez -- Lewis and Clark "camped out" for 862 days in a row -- no Holiday Inn for them. What a 'process of discovery.'

We now use the Gegorian Calendar -- based on earth's orbit of the sun -- not the lunar calendar.
Converting to this calendar was chaotic, because 11 days suddenly disappeared. Landlords, of course, wanted rent for those days -- and people were angry because it meant they were going to die 11 days earlier !
Catholic Countries: -- wed - oct 4, 1582 -- was followed by -- thurs, oct 15th
Of course - non-Catholic countries were slow in change because this time-keeper was honed by Pope Gregory. When they did change -- 12 days had disappeared.
