# How to get the day count between two given dates excluding Saturday and Sunday

**How to get day counts between two given dates excluding Saturday and Sunday.?**

Key for the given requirement is the **date** variable in ABAP itself. Actually date variable in ABAP is the count of days from 01.01.0001 to given date internally.

So if we pass the date variable value to an integer variable and display it, it will display the day count for 01.01.0001 to the given date.

e.g: DATA: lv_date TYPE d VALUE ‘00010201’,

lv_count TYPE i.

lv_count = lv_date.

WRITE:/ lv_count.

The output is 31.

Now to how to get the day of a date?

The answer again lies in the date variable. If we get the modulus of 7 for the date variable it ‘ll give the day as

2 -> Monday

3 -> Tuesday

4 -> Wednesday

5 -> Thursday

6 -> Friday

0 -> Saturday

1 -> Sunday

E.g. DATA: lv_date TYPE d VALUE ‘20120102′,

lv_count TYPE i.

lv_count = lv_date MOD 7.

WRITE:/ lv_count.

The Output is 2 i.e 01.01.2012 is a Monday.

Now the following Function Module can be used for getting the day count excluding Saturday and Sunday.

Hello, Rakesh.

Could you explain please what is the use of your function module?

Hello Andrei,

Its sample code only, I have use it for finding age of document (excluding Saturday and Sunday). The good part of this code is that it takes almost same time of execution for any set of dates.

Ok, I got it. But it only serves for exact purpose. I mean you calculate duration assuming that only Saturday and Sunday are weekends, right? What about holidays? Or countries where weekends are different from Saturday and Sunday? For instance, Israel has Friday and Saturday as weekends.

Reinventing the wheel is good. No, I'm not kidding. That is real good for understanding how the system works. And your code works well. And fast. But in general your task should be solved by FM DURATION_DETERMINE which returns duration between two days considering factory calendar.

Well your Point is fine. But Suppose that HR module is not implemented then, we can't use factory calendar. Again it’s a simple sample of code not a Reinventing anything. It just a exploration a data type D

.

Yes, Rakesh. I got it. Good explanation of type D. With pretty useful example. Thanks.

BTW, you do not need HR module to use factory calendar and to use mentioned FM.

Well thank for the information.I'll try to explore that ðŸ™‚

Hi All,

it will count the no of days between the given date and end date without Saturday and Sunday..thanks Rakesh.... i got same requirement.

Thanks,

Syam.

Hi Rakesh,

It is really very Usefull.

Hi Rakesh,

thank you for sharing this, but there is another quite simple and powerful function module FIMA_DAYS_BETWEEN_TWO_DATES which can handle your requirements and has some interesting options.

E.g.

Kind regards,

Hendrik

Hi Hendrik,

Thanks for the input.Yes it can handle leap year correctly. Here you should look at the interesting fact of the Date variable in ABAP.

Regards,

Rakesh.
