While many different calendar systems were developed by various civilizations over long periods of time, the calendar most commonly used worldwide is the Gregorian calendar. It was introduced by Pope Gregory XIII in 1582 and is largely based on the Julian calendar, a Roman solar calendar proposed by Julius Caesar in 45 BC. The Julian calendar was inaccurate and allowed the astronomical equinoxes and solstices to advance against it by approximately 11 minutes per year. The Gregorian calendar significantly improved upon this discrepancy. Refer to the date calculator for further details on the history of the Gregorian calendar.

Take note that the calculator respects order of operations, which is a mathematical convention that establishes which operations are performed before others in a mathematical expression that has more than one operation. The order is as follows: parentheses, exponentiation (including square roots), multiplications and divisions (from left to right), additions and subtractions (from left to right). With respect to order of operations, the value of the expression (Source: www.ets.org)

The Transfer Display button can be used on Numeric Entry questions with a single answer box. This button will transfer the calculator display to the answer box. You should check that the transferred number has the correct form to answer the question. For example, if a question requires you to round your answer or convert your answer to a percent, make sure that you adjust the transferred number accordingly.

The Box Plus Minus allows us to understand the player’s impact on the court in terms of the points differential (positive or negative) spread over 100 possessions. The Offensive and the Defensive have equivalent meaning but refer only to the offensive and defensive impact. As previously mentioned, the Box Plus Minus is calculated starting from the data obtained from a normal box score, even if, actually, the advanced statistics relating to the classic values of the box score will be used.

Number

Behind the first term there is small reasoning: wanting to compare the BPM of each player you can come across both high and low-minute players. Basically those with high minutes will have faced more critical moments of the game than the seconds. To give greater weight to the first ones, it was decided to add four 0-minute games in the calculation of the average. The total minutes are then divided by the number of games played plus four: this value has been set by Myers for the NBA. For the statistics that I calculate for Serie A, Euroleague and Eurocup I decided to add two 0-minute games instead, given that the total number of matches is much lower (30/34 games against 82).

Having said that the BPM value chosen for the Replacement Player is -2, the distance between that player and the one being analyzed is calculated with the first subtraction, then the result is multiplied by the percentage of minutes played and the ratio between the team game played and the total number of games to play (82 for the NBA, 30 or 34 for Serie A and Euroleague).
