Insert these as measures or use in formulas for new columns in a DAX table

For these examples TODAY() = 07/04/2017

DaysThisYear = DATEDIFF(DATE(YEAR(TODAY()),1,1),DATE(YEAR(TODAY())+1,1,1)-1,DAY)+1 // returns 365 
DaysThisFinancialYear = DATEDIFF(DATE(YEAR(TODAY()),7,1),DATE(YEAR(TODAY())+1,7,1)-1,DAY)+1 // returns 365_
DaysElapsedThisYear = DATEDIFF(DATE(YEAR(TODAY()),1,1),TODAY(),DAY)+1  // returns 97
LastDayOfThisMonth = FORMAT(EOMONTH(TODAY(),0),"DD")  // returns 30
