Excel equation to add hours to existing cell with date time data - excel

How to add 8 hours to existing cell
the cell content is "2020-02-14 09:41:52"
Lets say my column is in A1
I've tried
=(A1)+8
But I'm getting #VALUE!

If you are sure that your cell is formatted correctly as date time, then adding integers to date time values in Excel adds to the days. Trying =A1+8/24 should do the trick.

excel formula to fill rows based on start date and end date

Can you please help with a excel formula to have all the rows populated with dates inbetween the start date and end date already specifed. using the image below i want the dates populated automatically starting in cell A5 and going downwards towards the start date.
I want this automated so when changing the end date the rows update automatically.
expected output
Only paste this in A5 and pull down an amount of cells as the maximum days you think it will be, eventually.
IF(($B$2-(ROW()-5))>=$B$1;($B$2-(ROW()-5));"")

Excel date conversion to day of the week: not working after 1 row

I want to get days of the month corresponding to each particular dates in a column in Excel (Note that I am using the web version of office Excel).
The formula =TEXT(A2,"dddd") works correctly for the first row and then when applied to the later rows does not perform as needed. It returns the same date and not the weekday. I have checked the format of the cells, and it is all sent to General.
See the attached image for reference, the formula worked in C2, and not after that.
Note: I have inserted a table for the required range.
Not Recognizing d/m/yyyy
For cell A2 you can use this formula instead (in cell C2):
d/m/yyyy (Your Case)
=TEXT(DATE(VALUE(RIGHT(A2,LEN(A2)-FIND("/",A2,4))),VALUE(MID(A2,FIND("/",A2)+1,FIND("/",A2,4)-FIND("/",A2)-1)),VALUE(LEFT(A2,FIND("/",A2)-1))),"dddd")
m/d/yyyy (Someone else might need this.)
=TEXT(DATE(VALUE(RIGHT(A2,LEN(A2)-FIND("/",A2,4))),VALUE(LEFT(A2,FIND("/",A2)-1)),VALUE(MID(A2,FIND("/",A2)+1,FIND("/",A2,4)-FIND("/",A2)-1))),"dddd")

Incorrect calculations? Excel not performing correct time calculations

I'm simply trying to find the number of hours between the two dates and times, but excel won't account the date to the number of hours, and only calculates the 'hours' themselves.
Your format on cell B3 is wrong. You may have mistakenly copied the date format from the cells above to B3.
If you set your format to "General" on cell B3 and change the formula to
=ABS(B1-B2)*24
I think you'll get the result you're looking for.

Excel 2013 How to assign dates to cells

I'd like to assign dates to cells in a planner spreadsheet I have made.
Currently, the rows are months, the columns are days of the week, and each individual cells just have a number for the day of the month.
I don't want to display the full date in the cell, just have the cell "know" what date it is representing. One use of this could be to have the current day always highlighted in a different colour when opening the spreadsheet. Is this possible in Excel?
Looking at your question, the results would require to show multiple "dates" within the cell.
For January '16 for example, you would have 4 different type of dates as January has 4 Mondays (4;11;18;25). Is this what you're looking to achieve? Otherwise it is not possible to have excel figure out a single date unless you provide it with additional references in order to come up with a result.
Enter a date into a cell. Format the cell to show the part of the date you want to see. In the screenshot, column A contains full dates in each cell. A2 and down are formatted with the custom format code shown in column C
Excel still treats the dates as the underlying full dates in formulas, even though only parts of the dates are showing in the cell.

Excel date query

I have a cell at the top of the spreadsheet that contains the date (say Feb 2013). I want to create columns off of that "reference" cell. In other words, based off of that date, I want one of the columns to display. But when I attempt, this it simply does not auto-increment the date but displays some random date.
02/01/2013
02/02/2013
02/03/2013
..
..
02/28/2013
As far as excel is concerned, a date in excel is just a number incremented from some arbitrary day in the past. For example, type 2/5/2013 into any cell. Excel will automatically format this cell as a date. Now right click, and format the cell. Under the number tab, select general and you will see excel really has the date stored as 41310. Using this same principle, if you want to increment dates based off of a reference date, it can be done simply by =A1+1 assuming the reference date is in cell A1. For example, type 2/1/2013 in cell A1 and in column B type =A1+1. Now drag this cell down as far as you want. As long as column B is formatted as a date, it will increment day by day.
