Despite the fact that a majority of Americans view China as the United States’ greatest strategic adversary, what to do about the rise of the Chinese Communist Party’s influence across the globe remains a point of significant debate. This Vandenberg Coalition series dives into this question with leading experts in eight different regions, ranging from outer space and the economy to Africa, Latin America, the Middle East, Europe, the Indo-Pacific, and South Asia. In each installment, we cover China’s growing influence in the region, how it measures against American influence, how to define our relationship with the region in light of competing priorities, and what America can and should be doing to better protect and advance our national interests.

The concept of Leap Year and Leap Day has existed for over 2000 years, with the extra day added to our calendars in February every four years to account for the fact that the actual length of a year does not perfectly align to the 365 days of our modern Gregorian calendar. This misalignment means calendar dates would slowly drift from their intended seasons if no adjustment was made over time.
In this article, we will explore the science behind Earth’s actual orbit around the sun and rotation on its axis that necessitates the need for a Leap Year. We will detail the history of previous inaccurate calendars, how the modern Leap Year system was created, and some alternative solutions that have been suggested instead of our current traditional method of handling the extra quarter day each solar orbit.
The Science Behind Earth’s Orbit and Rotation
The need for Leap Years originates from a differential between two astronomical time spans - the sidereal year and the tropical year. A sidereal year refers to the time it takes the Earth to orbit the sun once relative to the fixed stars: approximately 365.25636 days. Over this orbital period, Earth’s position relative to the stars shifts slightly each day.
In contrast, the tropical year is measured between successive vernal (spring) equinoxes as Earth moves through its seasons: lasting roughly 365.24219 days. Each equinox lands Earth at the same place relative to its tilted axis and orbit around the sun rather than the fixed stars.
This tropical year dictates the actual seasons and calendar dates we experience on a yearly cycle. The ~20-minute difference between a sidereal and tropical year may seem insignificant, but it adds up over time when relying on consistent seasons and calendar years. Even this small differential means a typical 365-day calendar would become noticeably misaligned after just a few decades.
Early Attempts At Accurate Calendars
Humans have long understood the concept of a year’s length not precisely lining up with a whole number of days. Ancient Babylonian astronomers estimated the tropical year as 365.2467 days. They aimed to balance their 12 months of either 29 or 30 days through the addition of an extra 13th leap month called an intercalary month about every three years. But this method still resulted in the gradual drifting of seasons over decades.
The first major attempt to settle on a more accurate tracking of days and years came with the implementation of the Julian Calendar in Rome in 45 BC under Julius Caesar. It featured a standard year of 365 days with an extra day added to February every four years going forward. This aligned much closer to the tropical year by averaging out to 365.25 days when factoring in leap years. It also locked in dates of the winter solstice to December 25th and the spring equinox to March 25th.
The Julian Calendar served much of Europe and the Western world well for over 1500 years. It maintained equinox and solstice date alignment within a day into the mid-1500s. But those small errors still had added up by then, motiving Pope Gregory XIII to assemble top astronomers to develop an improved and more lasting solution.
The Creation of the Modern Gregorian Calendar
After the Council of Trent authorized Pope Gregory XIII to reform the calendar in 1582, astronomers proposed the Gregorian Calendar of the same year to better achieve synchronization with the tropical year. By skipping 10 days to realign the spring equinox date and also modifying the leap year rules slightly, the Gregorian Calendar resulted in a more accurate system expected to keep seasons on track within a day for the next 3300 years.
The new Gregorian Calendar leap year rules specify that years divisible by 100 are not leap years unless they are also divisible by 400. So years like 1700, 1800 and 1900 do not have a February 29th while 1600 and 2000 are considered leap years. This exception brings the average length of the Gregorian Calendar up from 365.25 days as in the Julian Calendar to 365.2425 days. Since the tropical year is now calculated as precisely 365.24219 days long, this minimum error should maintain seasonal date alignment well into the distant future.
Countries were slow to adopt the Gregorian Calendar after its 1582 debut however. It took over 360 years for it’s use to extend around the globe. The important 1752 British adoption also necessitated dropping 11 days in September to realign - leading to riots from people believing precious days of their lives were being taken by the government. Most Eastern Orthodox countries only switched from the Julian Calendar in the early 20th century.
How Leap Days Function
In both the Julian and Gregorian Calendars, the extra Leap Day is added onto the shortest month of February once every four years. This keeps the numbering alignment stable across other months while making the length of February also more comparable from standard years to leap years. Having all standard years be exactly 365 days also supports simpler financial calculations for items like interest accrual.
Every four years, February 29th emerges as Leap Day - considered an “intercalary” day not belonging to any week or month. Some proposed calendar adjustments aim to fix the date of Leap Day at the end of February or a different month entirely rather than existing between the 28th and March 1st. The rare Leap Day adds delight and excitement through fun traditions around the world, from women proposing to men in Ireland to special deals and events for those born on February 29th.
Alternative Proposed Leap Year Solutions
While the Gregorian Calendar system has worked effectively to keep our calendars aligned to the seasons, various alternatives have been suggested over the years to potentially refine the method of adding a leap day even further. But given the deeply embedded nature of our current calendar system in both traditions and technical integrations globally, massive worldwide changes are highly unlikely.
Some key alternative calendar formats that have been proposed include:
World Calendar: Prominent proposals in the early to mid-1900s floated the idea of a perpetual 12-month, equal-quarter calendar, with 365 days in 3 quarters and 366 days in the fourth quarter. Leap Day would fall on “Year Day”, as an additional day between December 30 and January 1st that does not belong to any week or month. However objections to lost Sabbaths by religious leaders and lack of business support have held it back.
364-Day Calendar: Removing a day from our calendars entirely every 5 or 6 years unless needed based on the equinox has been proposed to make all months equal lengths. But this would disrupt weekly cycles and financial calculations.
30-Day Months: Rather than adding full Leap Days every four years, adding an extra day to 30 days each year maintains even months while adding the needed day fraction annually. But financial/data systems would require heavy reworking for such frequent uneven lengths.
Adding Leap Week or Month: Instead of a single Leap Day per four years, some suggest adding an entire extra week or month through the year to minimize annual disruptions. But this can complicate year-on-year financial analysis and adds notable complexity to calendars.
Leap Seconds: Scientists have worked to differentiate between inconsistencies in astronomic timekeeping from Earth’s orbit versus its gradually slowing rotation. To handle the latter, occasional Leap Seconds added to Coordinated Universal Time help keep clocks in sync with the sun without needing adjustments to annual orbits or calendars.
Free-Floating Leap Week: Similarly, proposals of a free-floating 7-day mini-month added whenever needed based on equinox drift could simplify calendars. This would separate the timekeeping adjustment from public calendars. But financial/scheduling challenges persist around when the Leap Week would be placed each time.
Conclusion
In the end, no proposed alternative has shown enough definitive benefits over the current Gregorian Calendar and quadrennial February 29th Leap Day system to warrant attempting a global calendar overhaul. The Gregorian Calendar now reigns as the international standard and offers a simple yet reliable method for keeping our calendars aligned with Earth’s orbit and seasons indefinitely into the future with minimal disruptions every four years.
Leap Years and Leap Days originate from the subtle discrepancies between astronomical timekeeping measures from Earth’s rotation versus its orbit around the sun. While various solutions have aimed to perfect the balancing act of seasons, months, weeks and days across the years, the current four-year leap cycle supports stability across finances, records, traditions and more worldwide. The Gregorian Calendar’s ability to maintain seasonal alignment over thousands of years means this quadrennial quirk and delight of Leap Day is likely here to stay for the long run.

Lecture summary:
Part 1 of the Lecture focuses on the development of the right to self-determination as a rule of customary international law and its application to the Chagos Archipelago, Africa and the Commonwealth Caribbean. The adoption of Resolution 1514 by the General Assembly of the United Nations on December 14, 1960 was a decisive element in the development of the customary character of the right to self-determination. After that transformational development it was colonial peoples, not colonial powers, who determined their independence and its form e.g. whether based on a republican system or a UK parliamentary system. Thus, after that time the colonial powers were under an obligation to respect the right of colonial peoples to ‘freely determine their political status’, and any breach of that obligation would entail their international responsibility.
Part 11 addresses the status of the right to self-determination as a norm of jus cogens, and concludes that on the basis of the relevant evidentiary material, the right to self-determination is a peremptory norm of general international law.
Part 111 focuses on the right to self-determination in relation to the Occupied Palestinian Territory. Disappointment is expressed at the lack of clarity in the ICJ’s treatment in its recent Advisory Opinion of the jus cogens character of the right to self-determination in cases of foreign occupation.
