Salutations-Fiscal Calendar in Power BI

Hi Jerzee 

Different companies might have different ways of them deciding a financial year .

for the below example of calculated table you can create a fiscal calender staring from April 

Date Table = 
ADDCOLUMNS(
    CALENDAR(DATE(2015,4,1), DATE(2030,3,31)),

    -- Fiscal Year
    "Fiscal Year", 
        "FY" & FORMAT(YEAR([Date]) - IF(MONTH([Date]) < 4, 1, 0), "00"),

    -- Fiscal Year-Quarter
    "Fiscal Year-Quarter", 
        "FY" & FORMAT(YEAR([Date]) - IF(MONTH([Date]) < 4, 1, 0), "00") & " " &
        "Q" & 
        SWITCH(
            TRUE(),
            MONTH([Date]) IN {4,5,6}, 1,
            MONTH([Date]) IN {7,8,9}, 2,
            MONTH([Date]) IN {10,11,12}, 3,
            MONTH([Date]) IN {1,2,3}, 4
        ),

    -- Month Name (Text)
    "Month", FORMAT([Date], "MMMM"),

    -- Actual Month Number (Calendar Month 1 = Jan)
    "Actual Month Number", MONTH([Date]),

    -- Fiscal Month Number (April = 1, May = 2, ..., March = 12)
    "Fiscal Month Number", MOD(MONTH([Date]) + 8, 12) + 1
)

Hi Jerzee 

Try the sampe DAX calculated table below

CalendarTable =
VAR FinancialYearStartMonth = 7 -- set your financial year start month here (e.g., 7 = July)
RETURN
    ADDCOLUMNS (
        CALENDAR ( DATE ( 2015, 1, 1 ), DATE ( 2030, 12, 31 ) ),
        "Year", YEAR ( [Date] ),
        "Month", MONTH ( [Date] ),
        "Month Name", FORMAT ( [Date], "MMMM" ),
        "Year-Month", FORMAT ( [Date], "YYYY-MM" ),
        "Financial Year",
            YEAR (
                DATE ( YEAR ( [Date] )
                    - IF ( MONTH ( [Date] ) < FinancialYearStartMonth, 1, 0 ), FinancialYearStartMonth, 1 )
            ) + 1,
        "Financial Month",
            MOD ( MONTH ( [Date] ) - FinancialYearStartMonth + 12, 12 ) + 1
    )
