HOW TO CALCULATE WORKING HOURS AUTOMATICALLY WITH EXCEL?

Here's how it works: ** in the following figure is an example; When entering data in column B, the corresponding cell in column A is automatically populated with dates.

1；Enter the formula in cell B2: =if(a2<>"now(),2；Press Enter; Then, enter the data in cell A2; In cell B2, the date is automatically displayed.

excel automatically calculates the number of days based on the date as follows:

1. Enter the formula in cell F5: e5-d5.

2. Right-click in cell F5 and select Format Cells from the menu.

3. At this time, the cell setting dialog box will pop up.

4. In the dialog box, select Numeric.

5. Set the decimal place to 0.

6. Confirm the return.

1. UseData validityDefine the length of the data.

Use the mouse to select the range of data you want to enter, the dots"data"->"Validity"->"Settings"，"Validity conditions"Set to"Allowed""Text length""Equal""5"(The specific conditions can be changed according to your needs).

You can also define some prompt messages, error warning messages, and whether to turn on the Chinese input method.

etc., define the back point"OK"。

2. Use conditional formatting to avoid repetition.

Select column A, dots"Format"->"Conditional formatting", set the condition to "Formula=countif($a:$a,$a 1)>1", point"Format"->"Fonts"->"Color", select the red color and tap it twice"OK"。

Once this is set, you enter the data.

If the length is incorrect, there will be a hint, and if the data is repeated, the font will turn red.

3. If it is required to compare the data of the same row in columns A and B.

It is assumed that the first line is the header.

Click cell A2, click "Format" - >Conditional Formatting", set the condition as: "Cell Value" "Not Equal" = B2 dot "Format" - > Font " - > Color", select red, and click "OK" twice.

Use the format brush. Copy the conditional formatting of the A2 cells down.

4. If column A is compared with column B as a whole (i.e., the same data is not in the same row).

Assuming the first row is the header, click cell A2, click "Format" - >Conditional Formatting", set the condition as: "Formula" = countif($b:$b, $a 2) = 0 dots "Format" - > font - > color", select red, and click "OK" twice.

Use the format painter to copy the conditional formatting of the A2 cells downwards.

After setting according to the above method, the data in column AB is not colored, and the data in column A with column B without or column B with column A without is marked with red font.

Hello dear, how to calculate time in excel**1, first of all, in excel**, you can get the number of days between two dates by subtracting two dates directly. 2. Calculate the number of days between two dates, you can also use the function datedif function to complete, according to our data content, the formula is as follows: =datedif(a2,b2,"d"Next, let's take a look at the datedif() function:

Its syntax: =datedif(start date, end date, third parameter), the third argument can have several cases, and can return the number of days, months, and years of the interval, respectively. 3. In fact, the simplest thing is to directly subtract the two times to get the time difference between them.

Note, however, that these cells must be set to time format. 4. If it is to calculate the time of more than 1 day, we can not get the correct result by using this subtraction directly, the result will not show the number of days, and the normal time difference needs to be displayed by formatting the cells. Let's format the cell as "[h]:

mm:ss", where h plus square brackets can fully display the difference in hours of time, and without square brackets, only the difference in hours after deducting the days can be displayed. Hope it helps.

If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

1. If the display method is Thursday in Chinese, enter the following function =text(weekday(a2,1),) in the required box"aaaa"where a2 is the grid where the date is located, and the figure is 2015 1 29 after the 1 without a detailed explanation, just do it.

2. If it is English, it is like this=text(weekday(A2,1),"dddd")

3. If it is a number, it is operated like this="Week"&weekday(a2,2) can let excel automatically calculate the date in a few days.

If you want to set a countdown timer in Excel and you want it to update automatically according to the time of your computer, you can follow the steps below:

Open the excel program and enter the time you need to count down in a blank worksheet.

Enter in the cell"=now()"formula, so that you can get the current time to the segment.

Enter the "=A1-B1" formula in another cell, where A1 and B1 are the cells you enter for the time you need to count down and the current time respectively.

Drag the mouse and drag the formula to the cell where you want to display the countdown, and you can realize the function of automatic countdown.

In this way, Excel will automatically update the countdown according to the time on your computer. In addition, you can also use Excel's "Live Data" feature for the same purpose. Here's how:

Enter in the cell"= real-time data()."formula, so that you can get to the current time.

Enter the "=A1-B1" formula in another cell, where A1 and B1 are the cells you enter for the time you need to count down and the current time respectively.

Drag the mouse and drag the formula to the cell where you want to display the countdown, and you can realize the function of automatic countdown.

In both ways, you can set a countdown in Excel and have it update automatically based on the time of your computer. Please choose the appropriate method according to your preference.

The male slip type is:

left(b1,find("，b1)-1)-left(a1,find("Guess the teasing,",a1)-1)+ceiling((mid(b1,find("，b1)+1,9)-mid(a1,find(", letter Zhaodan",a1)+1,9))*3,>

Working 28 hours is considered a day, and it is too exploitative of labor.

Those who do not want to be slaves, rise up against cruel exploitation.
