Calendar with week numbers

A calendar is a system for calculating sufficiently large time intervals, which is based on the periodicity of the movement of celestial bodies. Solar calendars are based on the movement of the Sun, lunar calendars are based on the movement of the Moon, lunisolar calendars are based on the movement of the Moon and the Sun at the same time.

One of the important units of any calendar is the week. A week is a period of time of seven days. For a person who effectively plans his work activities, a week, as a unit of time, is of great importance.

Calendar history

The term calendar itself came to us from Ancient Rome and translated from the Latin calendarium - debt book. History says that it was customary for the Romans to repay debts and pay interest on them on the first days of the month, on the days of the so-called calends.

However, the first analogues of calendars appeared long before the foundation of the Roman Empire.

In the vicinity of the town of Nabta Playa, which is located about 800 kilometers from Cairo, perhaps the first annual calendar circle in the history of mankind was discovered. It was created by the semi-nomadic tribes of pastoralists who inhabited the territory of modern Egypt in those days. With the help of this circle, the starting point of which was the appearance of the star Sirius in the sky, the inhabitants of the tribe tracked the beginning of the rainy season. Heavy rainfall turned the hot desert into a real oasis with meadows ideal for grazing.

At about the same period of history, an analogue of the calendar appeared among the tribes that inhabited the lands of present-day Germany. In history, it has been preserved as the Gosek circle, the starting point of which was the day of the winter solstice.

The following references to the mechanisms of time calculation refer to Ancient Egypt. Here, the calendar year was the time interval between two adjacent heliacal risings of the star Sirius. The Egyptians needed a calendar to determine the moments of the floods of the Nile River, repeating from year to year. A natural phenomenon could destroy all the crops of the inhabitants of Ancient Egypt. But, knowing in advance when this would happen, the farmers harvested their crops in advance and prepared for the cultivation of the soil, which after the end of the floods became more fertile and pliable for cultivation.

It is noteworthy that the ancient calendars did not have a clear organization, and in different cultures they had an original structure. So, for example, the Celts divided the week into 9 days, among the Egyptians it consisted of 10, and the ancient Germans lived for long weeks, consisting of as many as 14 days.

Weeks consisting of 7 days first appeared in the Ancient East. Each day of the week was given the name of a celestial body: Monday - the Moon, Tuesday - Mars, Wednesday - Mercury, Thursday - Jupiter, Friday - Venus, Saturday - Saturn, Sunday - the Sun.

The seven-day week also corresponds to the biblical scriptures, according to which God was engaged in the creation of the world for six whole days, and on the seventh day he finally decided to rest.

The final concept of the seven-day week was established by the Romans. It all started with the fact that the astronomer Sosigenes of Alexandria, on the orders of Caesar, developed the so-called Julian calendar, which had 12 months and 365 days. Further, the Romans spread this calendar throughout the empire, from hot Egypt to the endless forests of Germany.

The Julian calendar lasted until the 15th century, after which Pope Gregory XIII replaced it with the Gregorian. It practically did not differ from its predecessor, but was more accurate and closer to the correct time for the change of seasons. Today, most countries in the world use the Gregorian calendar.

The need for the introduction of calendars and their analogues among the peoples of antiquity and the gradual movement of all civilizations towards a single organized calendar testify to the special relationship of people to time. A calendar is not only a great tool for organizing, but also an indispensable tool for recording important dates and events in history, allowing you to pass reliable information to future generations of people.

The calendar is just a tool with which we can manage our time productively. But in order for this tool to work, we must arm ourselves with effective time management techniques.

Effective time management techniques

Rule 1‑3‑5

The essence of the rule is that for a working day, limited in time, you can afford a certain number of tasks. Make it a rule to do:

  • one big task;
  • three medium tasks;
  • two small tasks.

Using this rule, you will quickly rake up the things that have piled on you, get rid of the emergency method of work, and in the future you will have time to do everything on time without unnecessary overwork.

Rule of Three

For those of you who find the number of tasks in the rule above overwhelming, talented writer and productivity consultant Chris Bailey offers an easier solution: pick your three most important tasks from your checklist and focus fully on completing them for the rest of the day. The next day - the next three tasks, etc.

10 minutes method

The hardest part of any task is getting started. There is a great way to fool your lazy mind: “I will do this for just 10 minutes, and after that I will rest.” We are sure that soon you will forget about the rest and work productively.

The Pomodoro Method

The system of the inventive entrepreneur Francesco Cirillo "The Pomodoro Method" has long conquered the world. You will need a timer. You set it to 25 minutes. You are productive. After 25 minutes, allow yourself a five-minute rest, and then return to work. After working this way for four cycles, you take a break for 15-30 minutes.

Method 90/30

The essence of the method is as follows: you devote 90 minutes to working on a specific task, after which you rest for 30 minutes. Then the cycle repeats, and the next 90 minutes you devote to another task. It is important that you devote the first working segment to the most important task before you.

The method has a scientific basis, its effectiveness has been tested by many successful people.

Method 52/17

A method for those who find 90 minutes of productive work exhausting. The technology is the same as in the 90/30 method, the time frame is different: 52 minutes of work, 17 minutes of rest.

Eating frogs

The method of the world famous coach Brian Tracy. In his terminology, “frogs” are not very pleasant tasks, the thought of completing which causes a complete breakdown in strength and motivation. Tracy advises to "eat the frog", that is, to do this task, at the very beginning of the working day. Further it will be easier - the author of the technique promises.

Kanban

A great way to visualize your workflow, originally from Japan. To implement it, you will need a sticker board, the working field of which must be divided into three columns with headings: “To do”, “I do”, “Done”. Next, stickers are taken, cases are recorded on them, after which the stickers are pasted onto the board in the section corresponding to the current state of the case. The speed at which stickers move across the board will clearly show you the effectiveness of your work.

2 minutes rule

The rule comes from David Allen's GTD (Getting Things Done) methodology. The bottom line is simple: tasks that take up to two minutes to complete are done immediately. This will unload your brain without occupying it with small things.

Fresh or fried

A method based on the philosophy of blogger Stephanie Lee. It translates as "Fresh or fried". It is based on the theory that when we wake up in the morning, we have a “fresh” brain, but during the day it is “fried”. The method is to solve the most difficult and most important tasks while the brain is “fresh”. We will leave simpler and more pleasant tasks to the “fried” brain.

For the method to be most effective, we should take 15 minutes before bed to plan for the next day, taking into account the above philosophy.

Tim Ferriss Method

A rather complicated, but incredibly effective method from American investor Timothy Ferriss. Consists of two postulates.

  • The 80/20 Rule (Pareto Principle): 80% of the work gets done in 20% of the time. The remaining 80% of the time is devoted to 20% of the remaining work. At the heart of the principle is concentration, which will allow you to do most of the work in the first hours. The rest of the time, you can relax a little and do routine work that does not require special concentration.
  • Parkinson's Law: work fills all the time allotted for it.

Whatever methods of effective time management you choose to organize your working day, each of them is based on your desire to constantly improve your professional level and change for the better.

One day - one task that brings you closer to the goal! One month, one small goal!
