DayNumberOfQuarter arguments

| Argument | Description |
| --- | --- |
| timestamp | The date to evaluate. |
| start\_month | By<br>specifying a start\_month between<br>2 and 12 (1, if omitted), the beginning of the year may be moved forward<br>to the first day of any month. For example, if you want to work with a fiscal<br>year starting March 1, specify start\_month<br>= 3. |

Examples and results:

These examples use the date format DD/MM/YYYY. The date format is specified in the SET DateFormat statement at the top of your load script. Change the format in the examples to suit your requirements.

Example 1:

`DayNumberOfQuarter('12/09/2014')`

Returns 74, the day number of the current quarter.

Example 2:

`DayNumberOfQuarter('12/09/2014',3)`

Returns 12, the day number of the current quarter.   
In this case, the first quarter starts with March (because start\_month is specified as 3). This means that the current quarter is the third quarter, which started on September 1.

Example 3:

Add the example script to your document and run it. Then add, at least, the fields listed in the results column to a sheet in your document to see the result.

`ProjectTable:` `LOAD recno() as InvID, * INLINE [` `StartDate` `28/03/2014` `10/12/2014` `5/2/2015` `31/3/2015` `19/5/2015` `15/9/2015` `] ;` `NrDays:` `Load *,` `DayNumberOfQuarter(StartDate,4) As DayNrQtr` `Resident ProjectTable;` `Drop table ProjectTable;`

The resulting table shows the returned values of DayNumberOfQuarter for each of the records in the table.
