Objective: Consolidate skills names for cell ranges; acquainted with the logic functions and functions category Date and time

Give examples of functions category Date and time are commonly used in data processing:

TODAY()– function to determine the current date, no arguments

DAY(date) – function to calculate the day of the date of

MONTH(date) – function to extract the month from a date

YEAR(date) – function to extract the year from date

DAYS360(start date, end date) – function for calculating the number of days between two dates

JOB 1.

1. Create a table on the model below (Table 28), rename Sheet1 "Personnel department" and enter the data in the table.

2. Enter the following formula:

• In cell C2, enter the formula =TODAY(). Set the date format with the name of the month

• In cell E8, enter the formula: =YEAR(D8), in cell F8 enter: =MONTH(D8) • The column G is calculated as the difference between the current year and year of birth, in the G8: =YEAR($C$2)-E8

• Column H is necessary to calculate the number of days between the date of joining and using the current DAYS360 and the resulting value divided by 365, in H8: =DAYS360(C8,$C$2)/365

• Copy the formula entered into all cells of the table. Data column H set the number format with one decimal

3. Format the data in cells C8:D21 (Format – Cells, Number, Date, and select the appropriate date in the table)

4. Cells for each column in the table create names of column names.

5. In cell C4, enter the formula =COUNTR(Name)(счётз()) to determine the number of values in a column Name

6. In F4 and F5, enter the formula to calculate the average age and seniority. As arguments to functions using names corresponding cell ranges.

7. Add a column with the name Sign. Enter in this column the cell formula =IF(G9<=35,1,0), which returns the number 1, if the value is less than or equal to the age of 35 and 0, if greater.

8. In cell C5 enter the formula the sum of the column Sign(Признак). 9. Take the last column of the table invisible by typing Format - Column - Hide. 10. Save the file in your folder.

JOB 2.

1. Create a document MS EXCEL.

2. Create a table corresponding to Table 29.

3. Make a list of your loved ones and enter their date of birth (day, month and year). Using the Number tab (field type, format Main), specify the format of numeric values for columns С format DD.MM.YYYY“.year” ( ДД.ММ.ГГГГ; D – ГГГГ“ .г”); for columns E format MMMM (ММММ); for columns F format D (Д); for columns G format DDDD (ДДДД).

4. Copy the date of birth on the 4th column to the left, using an absolute reference to the original cell. In the next column, calculate how much each spent years, months, days use the function roundeddown(ОКРВНИЗ()) and today (СЕГОДНЯ()).

5. For the 8 column in the table is necessary to calculate the number of days between two dates (date of birth and current) through a DAYS360 and the resulting value divided by 365.

6. For 9, 10 columns are calculations also use the DAYS360.

Table 29 – Use date and time functions

№	Name	Date of birth	Year	Month	Number	Day	Lived
							Years	Month	Days

4. Copy the original table on another sheet by using the Move/Copy. Remove the column values Year, Month, date, and day. Clean the format of these columns. Fill these columns using date and time functions. Enter the formula:

4.1. In cells of fourth column enter the formula using the allocation function, the date of birth of the year().

4.2. In cells of fifth column of the table input function selection of the month from the date of birth month().

4.3. In cells of sixth column of the table cell, type – function highlight the day of your birth day().

4.4. In cells of seventh column of the table, type – function highlight the day of the week from the date of birth WEEKDAY ().

JOB 3.

Logical function SUMIF()

1. Create ledger accounting records on which will be displayed at the specified account balance since the beginning of this month.

2. Fill in the table «Main Journal» on the model below (Table 30). 3. Table «Balance sheet» in a row, enters Account input 368, 110.102, 105, 222, 221. 4. In line Debit, c calculate sums on the accounts using the SUMIF() function. In the calculation formulas use absolute and relative addressing.
