Group by anniversary (Date)

[harshad_barge]

I have a dataset which has the join date of an individual. "Position From Date" and "Position To Date".

 My code is currently grouping by:

Employee Summary By Anniversary = GROUPBY(
'ORDINARY HOURS', 
'ORDINARY HOURS'[Employee_ID],
'ORDINARY HOURS'[Employee Name],
'ORDINARY HOURS'[Dim_Employee_Position.Anniversary date],
'ORDINARY HOURS'[Level],
"From Date", MINX(
CURRENTGROUP(),
'ORDINARY HOURS'[Calculation Date]
),
"To Date", MAXX(
CURRENTGROUP(),
'ORDINARY HOURS'[Calculation Date]
),
"Actual Pay", SUMX(
CURRENTGROUP(),
'ORDINARY HOURS'[Payroll.Gross Pay]
),
"Calculated Pay", SUMX(
CURRENTGROUP(),
'Ordinary Hours'[CalculatedPay]
)
)

I want to Group by the anniversary of "Position From Date" every year 

Example: From 1/7/2012- 27/6/2013 "Calculation Date" column and 28/6/2013 to 27/6/2014 and so forth
How would I translate this logic to DAX?
Please find the example dataset here
Expected Table:

Employee Name	Position From Date	From Date	To Date	Calculated Pay	Actual Pay
Randy	28/06/2010	1/07/2010	27/06/2010	$$	$$
Randy	28/06/2011	28/06/2011	27/06/2012	$$	$$
Randy	28/06/2012	28/06/2012	27/06/2013	$$	$$
Randy	28/06/2013	28/06/2013	27/06/2014	$$	$$
Randy	28/06/2014	28/06/2014	27/06/2015	$$	$$

Hi @harshad_barge ,

I downloaded the file and find that it is a zip file filled with xml files. I tried to import file but nothing success. Is it the right dataset?
