Return a value based on date start and date end

Need help please! 

 

I need to return a value based on a date range. I have two tables, one has the date (which i need to return the id) and the other has the date start and date end of the coresponding ids. I have made two smaller tables as an example. 

id table.PNGMy first table provides the date start and date end of each id. I need to populate the id column in the table below.

These tables are just mockups, I have a much larger tables (with more ids and dates) loaded into power bi already. I could do it in excel using a VLOOKUP but can not work out how to make it work in Power BI. 

 

Any help would be much appreciated!

If I name the first table to Intervals and the second to Dates you could try:

Id = 
CALCULATE(
       VALUES(Intervals[Id]);
       FILTER(
           Intervals;
           Intervals[Date_Start] <= EARLIER(Dates[Date])
           && Intervals[Date_End] >= EARLIER(Dates[Date])
       )
)
