Discussion Overview

The discussion revolves around the calculation of the number of days between November 10 and December 2, with participants sharing their differing counts and reasoning. The conversation touches on the use of software tools like Microsoft Excel for date calculations and explores potential misunderstandings related to calendar systems.

Discussion Character

  • Debate/contested
  • Mathematical reasoning
  • Technical explanation

Main Points Raised

  • Some participants assert that there are 21 days between the two dates, while including both November 10 and December 2 results in 23 days, and counting from November 10 as 0 leads to 22 days.
  • Others mention discrepancies in date calculations provided by Microsoft, with one participant noting that Excel indicates 22 days.
  • A participant expresses confusion regarding previous claims about the number of days between September 28 and October 25, suggesting that there are 27 days, not 17 as stated by another participant.
  • Another participant questions whether the previous claims are an inside joke, implying a misunderstanding or miscommunication.
  • One participant provides historical context about calendar changes, explaining how certain dates were skipped in different regions due to the transition from the Julian to the Gregorian calendar.
  • A participant shares a personal anecdote about a test drive expiration related to the date calculation, indicating that the issue is not significant but still perplexing.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the number of days between November 10 and December 2, with multiple competing views presented. Additionally, there is disagreement regarding the accuracy of previous date claims, leading to further confusion.

Contextual Notes

Participants reference the potential for misunderstandings based on how days are counted (inclusive vs. exclusive) and the historical context of calendar adjustments, which may affect perceptions of date calculations.

According to Microsoft there are 30.. I just count 23 :rolleyes:

..I don't need their software anyway :cool:

My copy of Excel tells me 22 days and so do my fingers. :)
 
That leaves me totally perplexed.

If Microsoft said there were 17 days between Sep 28 and Oct 25, I might understand it or if Microsoft said there were 17 days between Aug 28 and Sep 25, I might understand it. In both cases, you just set your calendar to the wrong year.

I can't think of any year that extra days were added into the calendar.

Edit: And, according to my fingers, it's been 92,488 days since the last time days were removed from the calendar.:biggrin:

Well, there are 21 days BETWEEN them, it's 23 if you include both Nov 10 and Dec 2 in your count, and 22 if you start from Nov 10 as 0 and count Nov 11 as 1, then end with Dec 2 as 22. :biggrin:

Well, it seems like Microsoft's calendar is as good as their spell-checker that I've caught misspelling things. :smile:

Is this an inside joke or something? There are 27 days between Sept. 28 and Oct. 25 - that's nowhere close to 17. With August/September, it's 28 days difference.

The standard Excel function gives the "difference" between the dates and this is what most people would be interested in and, even though the OP said "days between," she probably meant difference as in "number of days until such and such."

I think Monique should elaborate on the problem - i.e. when, where and how does it arise.
 
Yeah, I should have said including those days. The problem was that I activated my Office Test-drive on Nov 10, the test drive is for 30 days, the day before I still had 8 days of test drive left, the next day it expired :confused:

Not a big problem, it's just really weird :rolleyes:

Depends where you live. In Italy, Spain, Portugal, and Poland, Oct 4 1582 was followed by Oct 15, 1582. In Great Britain (and the American British Colonies), Sep 2, 1752 was followed by Sep 14, 1752.

The original Julian calendar slightly miscalculated leap years by inserting them every four years. The current Gregorian calendar skips leap years in every year ending in '00 unless the first two digits of the year are divisible by four. In other words, the year 2000 was a leap year. The year 2100 won't be. The year 1600 was a leap year, but the year 1700 shouldn't have been.

It took a while before the first day of Spring, etc, drifted far enough away from it's traditional date that people felt they had to fix it - hence having to suddenly subtract so many days out of the calendar.

The fix to the calendar also moved New Year's Day from Mar 21 to Jan 1.

In fact, back when Lincoln and Washington each had their own holidays, it was fun to ask people what the date was on the day when Washington was born (it was Feb 11, 1731 - not Feb 22, 1732 -- the colonies still used the Julian calendar when Washington was born). Now, with the Lincoln and Washington holidays merged into one Monday holiday that doesn't correspond to either's birthday, you ask someone what the date was on the day Washington was born and they just respond, "How the heck should I know!"
