Check If a date is between two dates from a different table

Hi There,

This might be a very simple topic but I am struggling with DAX. Could someone please help.

I have a table [Table_CallLog] having one of it's column named 'Call_DateTime'. I have another Table [Table_DSTReference] with three columns, Year, DST_StartDateTime and DST_EndDateTime. Which gives a reference to Start and End of Daylight saving time for several years.

What I tried doing is..

Step 1. Added a Column [named as Year_CallLog] (In Source SQL itself) to get Year(Call_DateTime).

Step 2. Joined Table_CallLog with Table_DSTReference based on Year_CallLog to Year (Many to 1).

Step 3. (This is where I'm stuck) Trying to add a measure/calculated column in Table_CallLog, which will check

if(Table_CallLog.CallDateTime >=  Table_DSTReference.DST_StartDateTime && Table_CallLog.CallDateTime <  Table_DSTReference.DST_EndDateTime, "Summer", "Winter")

Is this correct syntax? seems I'm unable to write it that way.
