Sep 8, 2016 - We show how Excel turns dates into serial numbers for easier calculations. In column C to convert Excel's serial-number dates to Julian dates. Convert serial number to date with formula. You can also convert serial number to date with formula in Excel. Please do as follows. Select a blank cell (says cell B2) adjacent to the serial number cell you need to convert to date, then enter formula =TEXT(A2,'m/d/yyyy').
In SQL:
In SSIS, see here Mac os library file photo wall frames.

The marked answer is not working fine, please change the date to '1899-12-30' instead of '1899-12-31'.

You can cast it to a SQL smalldatetime:
SQL Server counts its dates from 01/01/1900 and Excel from 12/30/1899 = 2 days less.

this actually worked for me
(minus 1 more day in the date)

Found this topic helpful so much so created a quick SQL UDF for it.

SSIS Solution
'The DT_DATE data type is implemented using an 8-byte floating-point number. Days are represented by whole number increments, starting with 30 December 1899, and midnight as time zero. Hour values are expressed as the absolute value of the fractional part of the number. However, a floating point value cannot represent all real values; therefore, there are limits on the range of dates that can be presented in DT_DATE.' Read more
From the description above you can see that you can convert these values implicitly when mapping them to a
DT_DATE
Column after converting it to a 8-byte floating-point number DT_R8
.Use a derived column transformation to convert this column to 8-byte floating-point number: Manual samuel windows 10 download.
Then map it to a

I had to take this to the next level because my Excel dates also had times, so I had values like this:
(also, to complicate it a little more, my numeric value with decimal was saved as an NVARCHAR)
The SQL I used to make this conversion is:

In addition of @Nick.McDermaid answer I would like to post this solution, which convert not only the day but also the hours, minutes and seconds:
For example
42948.123
to2017-08-01 02:57:07.000
42818.7166666667
to2017-03-24 17:12:00.000

You can do this if you just need to display the date in a view:
CAST
will be faster than CONVERT
if you have a large amount of data, also remember to subtract (2) from the excel date: https://intensivebeer513.weebly.com/why-cant-i-download-anything.html.If you need to update the column to show a date you can either update through a join (self join if necessary) or simply try the following:
You may not need to cast the excel date as INT but since the table I was working with was a varchar I had to do that manipulation first. I also did not want the 'time' element so I needed to remove that element with the final cast as 'date.'
If you are unsure of what you would like to do with this test and re-test! Make a copy of your table if you need. You can always create a view!

Try the approach discussed in the following link, which involves creating a function that performs the converstion and applying the function in your SQL.

This worked for me because sometimes the field was a numeric to get the time portion. https://ventaste.weebly.com/download-android-50-for-samsung-tab-4.html.
