Calendar Factory Fired Me For Taking a Day Off 4 Quiz

Answer: February 11, 1731

George Washington's birthday gets very confusing because when he was born the Julian Calendar was in use in the Colonies and Great Britain, and by that calendar he was born on February 11, 1731. Britain didn't adopt the Gregorian Calendar until September 2, 1752, by which time they had to skip 11 days, so everyone who went to bed on September 2nd woke up on September 14th according to the new calendar. And the year date of Washington's birthday changed from 1731 to 1732 because under the Julian calendar, the new year began on March 25, so when the switch occurred, January 1 became the official start of the year. February 12, 1734, was exactly 75 years before Abraham Lincoln was born.

Answer: It abolished weekends

That Soviet experiment's calendar introduced the 5-day week ("Nepreryvka") in which weekends were eliminated, and that 5-day week was color-coded by worker group so that factories could run non-stop. This was chaotic for families as husbands, wives, and friends had different rest days. So, it was replaced December 1931 to June 1940 with the 6-day week ("Shestidnevka") in which the 6th, 12th, 18th, 24th, and 30th of each month were rest days. So that sounds like the problem was solved of different rest days in a family, however there was still the wobbliness of rest days falling on different days of the week all the time. So, for that reason and others (religious Sundays a thing of the past, 2-day weekends making certain leisure activities impossible, non-existent "February 30" rest day, etc.) the experiment remained unpopular and was given up in 1940.

Answer: Sunday

It's just simple math really, since if a month starts on a Sunday, then the 1st of that month is a Sunday of course, and so counting forth:
The 2nd is a Monday, the 3rd is a Tuesday, the 4th is a Wednesday, the 5th is a Thursday, the 6th is a Friday, the 7th is a Saturday, the 8th is a Sunday, the 9th is a Monday, the 10th is a Tuesday, the 11th is a Wednesday, the 12th is a Thursday, the 13th is a Friday. And there is a maximum of three Friday the 13ths in a single year. Also, there is a minimum of one Friday the 13th in every year.

Answer: The Holocene Calendar

Some scientists have proposed a system where the year 2024 AD would be labeled as year 12024 HE (Holocene Era- from ancient Greek hólos, meaning "whole" and kainós, meaning "recent") which adds 10,000 years to the current AD count. The idea is that the calendar starts at approximately the beginning of human civilization; this for one thing avoids the split between BC and AD.

The basis of the BC/AD split was based on an inaccurate 6th-century calculation of the birth of Jesus in the first place. The start of the Holocene Calendar aligns with the start of the Holocene Epoch-the geological epoch coincides with the dawn of agriculture, permanent settlements, and the first civilizations after the last Ice Age.

Answer: The week with the first Monday of the Gregorian Calendar year is Week 1 of the new ISO year.

The rule of determining Week 1 of the ISO year is that the week that contains the first Thursday of the Gregorian year will be considered Week 1 of the new ISO year. So, taking the transition from 2026 to 2027 in the ISO year, we see that December 31st of 2026 is a Thursday. That means the first day of 2027 is a Friday. The first Thursday of the Gregorian 2027 will be on January 7, 2027, so that week will be the first ISO week. That week encompasses Monday, January 4 (remember that every week starts on a Monday) through Sunday, January 10th, 2027. That week is Week 1 of the ISO year 2027. And so, the last week of ISO Year 2026, that is Week 53, will be Monday, December 28th, 2026, to Sunday, January 3rd, 2027.

This system is actually a real implementation in the finance and accounting world, the logistics and product management world, the manufacturing and inventory worlds, and certain data science worlds (like Python, SQL, and Power BI). The system makes every fiscal period (quarter, year) have a clean, whole number of weeks, making financial comparisons more accurate. Managers in in one part of the world can tell supplier in other parts of the world to deliver a product in "Week 43," and both sides will know it means the week starting on the specific Monday of that week. Production schedules are based on weekly batches, avoiding the confusion of months that have either 30 or 31 days.

Answer: "Worldsday" always falls on December 31st a Saturday, the last day of any given year

Perhaps the most unique thing about the World Calendar is the designation of "Worldsday" an intercalary day with no weekday designation. It occurs every year the day after December 30th. Which you might assume would be December 31st, however, in the World Calendar there is no December 31st. It doesn't exist anymore. December only has 30 days in the World Calendar. The day after it is Worldsday, and the day after Worldsday is January 1st of the new year. Worldsday is a sort of no-man's land with none of the seven normal weekdays we know attached to it. Its purpose is similar to the leap year function. But instead of a February 29th every four years, Worldsday is that "extra day" that makes the math work without disrupting the perfect 7-day week cycle of the rest of the World Calendar.

Those 4 equal quarters of 3 months each are divided this way: the first month of every quarter is 31 days, and the 2nd and 3rd months of each quarter are 30 days. So, every quarter's first month: January, April, July, and October all begin on a Sunday, and they are all 31 days. And all the other months, February, March, May, June, August, September, November and December are 30 days.

Since every quarter begins on a Sunday, January 31st is always a Tuesday, thus making every February 1st a Wednesday.

One more thing, the World Calendar, like the Gregorian's has a leap year every four years. In leap years, The World Calendar adds a second intercalary day called Leapyear Day placed after Saturday, June 30 and before Sunday, July 1. Leapyear Day, like Worldsday, has no weekday assignation.

Answer: The tropical year

The tropical year, also called the solar year, determines the seasons, and is approximately 365.24 days. A lunar year, based on twelve cycles of the moon, is about 354 days, roughly 11 days shorter than the tropical year.

The Gregorian calendar leap year allows the calendar to match up with the tropical year, which is closer to 365 1/4 days. But because it's not exactly caught up, that's the reason leap years happen only during years that are divisible by 4... unless they are divisible by 100, in which case they also need to be divisible by 400. Using that system, the years 1900, 2100, and 2200 are not leap years, but 1600, 2000, and 2400 are. This specificity nudges the Gregorian calendar year ever so much closer to the tropical year.

Answer: Sunday

The possible weekdays for January 1 of a century year are limited to Monday, Wednesday, Friday, and Saturday (and occasionally Thursday, as in 2500). Sunday never occurs. This is because of how leap years work in the Gregorian calendar. In the Gregorian system, most years shift the weekday forward by 1 day, but then every four years, the leap year shifts it by 2 days.

A normal 100-year span (like 1700-1799) has 76 normal 1-day shifts and 24 leap years which means 24 extra shift days. So that years has 124 shift days total. 124 shift days divided by 7 (days in a week) is 17 weeks plus 5 extra days.
Each century thus normally shifts the starting weekday forward by 5 days.
The next thing that plays a part in the formula is that century years (like 1700, 1800, 1900, 2100) are NOT leap years. However, in the case of century years that ARE divisible by 400 (like 1200, 1600, 2000, etc.)-those century years ARE leap years. So, keep that in mind as we proceed:

After the Gregorian calendar was adopted in 1582, the first century year we got to was 1600 a leap year century. January 1st in 1600 was a Saturday. (You can look it up). Let's also note easily enough that 1700 began on a Friday and 1800 began on a Wednesday. Now let's look at the pattern and follow the rules of the Gregorian calendar:

Ordinarily, from a non-leap year century year like 1700, the next century year will begin on a weekday 5 days later than the previous century began. And we see this to be true as January 1, 1700, was a Friday and January 1, 1800, was a Wednesday, five days later. January 1, 1900 (another non-leap year century year) was a Monday, again a 5-day shift after Wednesday. Another 5-day shift gets to Saturday, January 1, 2000. But yes, now we are at 2000 which WAS a leap year century, so the shift forward is 6 days instead of 5, and indeed we note that January 1, 2100, will be a Friday.

The pattern continues:
January 1, 2200 is Wednesday (5-day shift to next century year)
January 1, 2300 is Monday (5-day shift to next century year)
January 1, 2400 is Saturday (6-day shift instead of 5 since 2400 is a leap year)
January 1, 2500 is Friday (5-day shift to next century year)
January 1, 2600 is Wednesday (5-day day shift to next century year)
January 1, 2700 is Monday (5-day shift to next century year)
January 1, 2800 is Saturday (6-day shift instead of 5 since 2800 is a leap year)
January 1, 2900 is Friday (+2 days shift from a leap year over the full century cycle results in a net +5 from prior non-leap pattern continuation)
January 1, 3000 is Wednesday (+5 days, since 3000 is not a leap century)
January 1, 3100 is Monday
January 1, 3200 is Saturday
January 1, 3300 is Friday

The Gregorian calendar resets itself every 400 years and we see that as the pattern of Wednesday, Monday, Saturday, Friday repeats.

Answer: a Martian calendar

A Martian "year" is about 687 Earth days, so any Mars colony that we set up on that planet will need its own calendar at some point. Luckily, aerospace engineer Thomas Gangale foresaw this possibility in 1985, and proposed the Darian calendar. It has 24 months and alternates 27 and 28 sols (Martian days of about 24 hours and 39 minutes) each.

Answer: "Calendar Girl", by Neil Sedaka

In December 1960, Neil Sedaka's "Calendar Girl" was released and peaked at #4 on the U.S. Billboard Hot 100 in February 1961. It was a #1 hit on Canada's chart that year, and hit #3 in Australia. The lyrics follow the simple idea of linking each of the 12 months of the year to an endearing thing about the girlfriend:
January: "You start the year all fine"
February: "You're my little Valentine"
March: "I'm gonna march you down the aisle"
April: "You're the Easter bunny when you smile"
May: "Maybe if I ask your dad and mom"
June: "They'd let me take you to the junior prom"
July: "Like a firecracker I'm aglow"
August: "When you're on the beach you steal the show"
September: "I light the candles at your sweet sixteen
October: "Romeo and Juliet on Halloween"
November: "I'll give thanks that you belong to me"
December: "You're the present 'neath my Christmas tree"

All the way up to 2025, there has never been another song with the word "calendar" in the title to enter the Billboard Hot 100.
