**** Any Calendar Reform which proposes any extra days outside of a 7 day weekly cycle will result in a work day falling on the 7th Day Sabbath. ****
There have been two such proposals, 1 = Mastrofini - (28 day 13 month, xtra day/year, 2 xtra days/Leap Year) and 2 = Hanke/Henry (30-30-31 day 12 month, Leap Week every 5 or 6 years),
with other people reprising or offering slight variations (1 = Comte reprise, Cotsworth/EastmanKODAK reprise, 2 = World Calendar 31-30-30 xtra day/year, 2 xtra day Leap Year variation).
Pope Gregory XIII unveiled his Gregorian calendar in 1582. With it's Leap Years it has kept in sync with the seasons for more than 400 years.
It isn't absolutely perfect, there's still a 30-second drift every year, which means it will be off by one day every 3,236 years.
The Gregorian calendar, also called the European calendar by some, is the dominant calendar used on Earth for trade and international relations.
Within the Gregorian Calendar system, the beginning of a week is not synchronized with the beginning of a year. Consequently, the Gregorian Calendar is based on 14 individual cyclic Calendars,
7 for non-leap years and another 7 for Leap Years each depending on which day of the week the 1st of January falls after the previous year's date ends.
Memory Mnemonic - 30 days has September, April, June and November, all the rest have 31 except February alone which has 28 days clear and 29 in each Leap Year
Leap Year Rule - generally every 4th year, if the year is divisible by 4 with no remainder. Remainders are accumulated to create a Leap Year.
Century Leap Year Rule - generally every 4th century. Exception - If the year is divisible by 100 with no remainder, but not divisible by 400 with no remainder, that year is NOT a Leap Year.
[e.g 1800/100 = 18 possible LY, but 1800/400 = 4.5, so 1800 is NOT a Leap Year.] [e.g 2000/100 = 20 possible LY, but 2000/400 = 5, No remained so 2000 is a Leap Year.]

So how are the seasons defined? Countries further away from the Equator have four seasons defined as:
Spring, which begins when the Sun is exactly above the Equator, so night and day are equal lengths. This is called an equinox and occurs twice a year, once in Spring and once in Autumn.
(20 or 21 March in the Northern Hemisphere and 22 or 23 September in the Southern Hemisphere).
Summer, which begins on the day of the year with the longest daylight hours
(20 or 21 June in the Northern Hemisphere and 21 or 22 December in the Southern Hemisphere).
Autumn also begins on an equinox
(20 or 21 September in the Northern Hemisphere and 22 or 23 March in the Southern Hemisphere).
Winter begins on the shortest day of the year with the longest night
(20 or 21 December in the Northern Hemisphere and 21 or 22 June in the Southern Hemisphere).
In Australia, the Bureau of Meteorology starts the seasons on the first of the month. This is just for simplicity.
Spring begins on 1 September, Summer on 1 December, Autumn on 1 March and Winter on 1 June.
(a little over three weeks before each actual event? Would have been closer to make it the beginning of the month after the actual event. October, January, April, July)

International Standard ISO 8601 is an international standard for the formatting of dates and times.
It has been adopted by most of the major countries around the world, either directly or as equivalent national standards.
There are a number of options in the standard but the basic idea is that a date is normally represented in the Year-Month-Day format YYYY-MM-DD
with the Year being four digits and the Month and Day both two digits. Similarly, a time is shown as Hour:Minute: Second with each being a two-digit number 24:59:59
Leading zeros are inserted as required to make each part of a date or time up to the specified number of digits. e.g. 2024-07-16 24:59:59
UTC: The World's Time Standard (Coordinated Universal Time) - Time Zone (Coordinated Universal Time) UTC-1 November Military
