| inlunarweek('12/01/2013', '14/01/2013',
0)
|
Returns True. Because the value of timestamp, 12/01/2013 falls in the week 08/01/2013 to 14/01/2013. |
| inlunarweek('12/01/2013', '07/01/2013',
0)
|
Returns False. Because the base_date 07/01/2013 is in the lunar week defined as 01/01/2013 to 07/01/2013. |
| inlunarweek('12/01/2013', '14/01/2013',
-1)
|
Returns False. Because specifying a value of period_no as -1 shifts the week to the previous week, 01/01/2013 to 07/01/2013. |
| inlunarweek('07/01/2013', '14/01/2013',
-1)
|
Returns True. In comparison with the previous example, the timestamp is in the week after taking into account the shift backwards. |
| inlunarweek('11/01/2006', '08/01/2006',
0, 3)
|
Returns False. Because specifying a value for first_week_day as 3 means the start of the year is calculated from 04/01/2013, and so the value of base_date falls in the first week, and the value of timestamp falls in the week 11/01/2013 to 17/01/2013. |

Add the example script to your app and run it. Then add, at least, the fields listed in the results column to a sheet in your app to see the result.
This example checks if an invoice date falls in the week shifted from the value of base_date by four weeks.
TempTable:
LOAD RecNo() as InvID, * Inline [

10/12/2012

InvoiceData:
LOAD *,

Resident TempTable;
Drop table TempTable;

The resulting table contains the original dates and a column with the return value of the inlunarweek() function.
The function returns True for the value of InvDate5/2/2013 because the value of base_date, 11/01/2013, is shifted by four weeks, and so falls in the week 5/02/2013 to 11/02/2013.
