    Hi John2029 ,

     

    Please try:

    Date Tab 2 = 
VAR _t =
    ADDCOLUMNS (
        'Table 2',
        "DateDiff",
            VAR _tab1 =
                LOOKUPVALUE ( 'Table 1'[Date Tab 1], [Country], [Country] )
            RETURN
                DATEDIFF ( [Date Tab 2], _tab1, DAY )
    )
VAR _minDiff =
    MINX ( FILTER ( _t, [Country] = EARLIER ( 'Table 1'[Country] ) ), ABS([DateDiff]))
RETURN
    [Date Tab 1] + _minDiff

    Output:

Dear Evelyn9,

Thank you very much for your help and for this solution. This is very helpful ! I am sorry in advance to ask if you would you have a suggestion if in Table 1 there would be multiple countries with the same name?
For example if there was two countries with the name Afghanistan? As I understand the countries in table 1 must have a unique name or you would get the message: "A table of multiple values was supplied where a single value was expected."
I wonder if there would be a possibility to have the following output?

Thank you, and thank you again very much for your initial solution that answers the initial question. 
Best regards,
