HI Hossein,

If you are using a SQL server then you could create this function (found on Stack Overflow) and use it to convert the date?

CREATE FUNCTION [CalculatePersianDate] ( @intDate DATETIME )
RETURNS NVARCHAR(max)
BEGIN

DECLARE @shYear AS INT ,@shMonth AS INT ,@shDay AS INT ,@intYY AS INT ,@intMM AS INT ,@intDD AS INT ,@Kabiseh1 AS INT ,@Kabiseh2 AS INT ,@d1 AS INT ,@m1 AS INT, @shMaah AS NVARCHAR(max),@shRooz AS NVARCHAR(max),@DayCnt AS INT
DECLARE @DayDate AS NVARCHAR(max)

SET @intYY = DATEPART(yyyy, @intDate)

IF @intYY < 1000 SET @intYY = @intYY + 2000

SET @intMM = MONTH(@intDate)
SET @intDD = DAY(@intDate)
SET @shYear = @intYY - 622
SET @DayCnt = 5

IF ( ( @intYY - 1992 ) % 4 = 0) SET @Kabiseh1 = 0 ELSE SET @Kabiseh1 = 1

IF ( ( @shYear - 1371 ) % 4 = 0) SET @Kabiseh2 = 0 ELSE SET @Kabiseh2 = 1

SET @m1 = 1
SET @d1 = 1
SET @shMonth = 10
SET @shDay = 11

IF ( ( @intYY - 1993 ) % 4 = 0 ) SET @shDay = 12


WHILE ( @m1 != @intMM ) OR ( @d1 != @intDD )
BEGIN

  SET @d1 = @d1 + 1
  SET @DayCnt = @DayCnt + 1

  IF
  (@d1 = 32 AND (@m1 = 1 OR @m1 = 3 OR @m1 = 5 OR @m1 = 7 OR @m1 = 8 OR @m1 = 10 OR @m1 = 12))

  OR
  (@d1 = 30 AND @m1 = 2 AND @Kabiseh1 = 1)
  OR
  (@d1 = 29 AND @m1 = 2 AND @Kabiseh1 = 0)

   SET @m1 = @m1 + 1
   SET @d1 = 1

Hi, I had the same problem and solved it by loading a calendar table with Gregorian and persian dates and then using this formula:

FieldValue('PersianDate',FieldIndex('Date',YourDateToBeConverted))

Date and PersianDate are field names of the mentioned table.

Hope this proves to be useful
