For Science
	
		Science starts in school, where currently, children learn the "old" Gregorian Calendar. "Learning", in this case, means learning how to use it,
		not learning how it works. This is because the Gregorian Calendar is inherently inconsistent and illogical.
	
	
		When learning the Lukashian Calendar, children make a direct connection with Astronomy, because the days and years correspond to
		actual solar days and
		actual solar years. This way, children don't just learn about the calendar, they also learn about Astronomy!
	
	
		The Lukashian Calendar is easy to teach, because the mechanism is simple and consistent. Children can create their own dummy calendars, with their own years and days, allowing
		them to play with the mechanism and explore how it works. This is a much more natural way of learning, that leads to actual understanding, rather than just knowing how to use it.
	
	To Mars & beyond!
	
		Have a look at this talk from the 28th Annual Convention of the Mars Society, where our founder explains the mechanism,
		how it applies to Mars and how it can be used in Analog Missions on Earth.
	
	
		The Lukashian Calendar embraces the fact that days and years have variable durations, instead of constant ones. The mechanism does not make
		any assumptions about how long a day or a year is, or how many days a year has. It is therefore easily possible to plug in the durations of days and years on Mars instead of Earth, in order
		to create an instance of the Lukashian Calendar for the upcoming Mars Settlement that is accurate with respect to Martian astronomy. Let's see what this would look like.
	
	
		The Earth takes approximately 31.6 million seconds to orbit the Sun. During that time, it rotates approximately 365.25 times around its own axis, with each day
		lasting approximately 86400 seconds:

		Mars takes approximately 59.3 million seconds to orbit the Sun. During that time, it rotates approximately 668.60 times around its own axis, with each day

		As we can see, it makes no difference how long the years and the days are, or how many days are in a year. The mechanism applies universally.
	
	
		On Earth, a week is simply a period of 10 days: 7 working days and 3 weekend days. There are no months and the weekdays don't have names,
		like Monday or Tuesday. We can simply use the last digit of each day to tell which day of the week it is. The final week of the year lasts
		5 or 6 days (day 361 to day 365/366):

		On Mars, the only differences are that the days are slightly longer and the final week lasts 8 or 9 days (day 661 to day 668/669):

		As on Earth, the time of day is expressed as the proportion of the day that has passed, which is represented in terms of
		basis points (beeps). A beep is one ten-thousandth of a day.
		On Earth, this is around 8.6 seconds. On Mars, this is around 8.9 seconds.
	
	The Big Questions
	
		On Earth, a year runs from southern solstice to
		southern solstice, because this is a natural moment on
		Earth for one year to end and another to start. The particular southern solstice that was chosen to be the first (i.e. the start of
		the Lukashian calendar on Earth), is the one 5925 years ago. This number was chosen for three reasons:
	
	- All of human history fits in the calendar.
- The last two digits of the Lukashian year are the same as the Gregorian year for most of the year.
- The turn of day is during nighttime for the vast majority of Earth's population.
		As you can read in the detailed explanation of these reasons, the start of the calendar
		needs to coincide with both the turn of year and the
		turn of day.
	
	
		In order to determine the start of the Lukashian Calendar for Mars, we could consider the first reason. All of
		human history on Mars should fit in the calendar,
		which would require the calendar to start at least about 70 years ago.
	
	
		The second reason (the last two digits matching the Gregorian Calendar), seems less relevant. For the third reason, the outcome is going
		to depend on the exact location of the landing zone and the first Mars Settlement. This location would have to face away from the Sun
		during the turn of day.
	
	
		An implementation of the Lukashian Calendar for Mars requires us to answer the following three questions:
	
	- What should a year be on Mars? A rotation of Mars around the Sun, yes, but at which exact instants should one start and end?
- What should a day be on Mars? A Martian Sol, yes, but at which exact instants should one start and end?
- When should the calendar start counting? When is the first day and the first year?
		Choosing the answers to these questions will require close cooperation with organizations wishing to be involved in shaping the Mars Mission.
		These organizations can then also play a role in the continued governance of the calculations that establish the exact durations of days
		and years on Mars. The Lukashian Calendar can do its part, but settling Mars is a job that we need to achieve together.
	
	Analog Missions
	
		While the above questions are being answered, analog missions on Earth can already start using the Lukashian Calendar, in order to practice and evaluate it,
		and they can use the Earth implementation in doing so. After all, analog missions do take place on Earth!
	
	
		Analog astronauts can use Lukashian days and years, and keep time using the Lukashian clock, while still being in sync with the daily and seasonal cycles of
		Earth. The Lukashian Calendar is the only calendar that allows this and the experience of analog astronauts will be nearly identical to that of actual Mars settlers.
	
	
		If you are interested in setting up an analog mission with the Lukashian Calendar, please contact us, and
		we can help you figure out requirements, test scenarios and other implementation details.
	
	
		Colonizing a new planet means starting from scratch. Let's not burden ourselves with yet another complex calendar that makes no sense.
		When we have a greenfield, let's get it right!
