INTCK() Function in SAS is used to find Difference between two dates in Timestamp. INTCK() Function in SAS calculates difference between two dates , INTCK() function also finds difference between two datetime and timestamp. Number of working days between two dates in SAS is also accomplished using** INTCK **function Let’s see an Example of each.

- INTCK() Function in SAS – difference between two dates in days, weeks, months & year
- INTCK() Function in SAS – difference between two datetime in seconds, minutes, & hours
- Number of Week days in SAS –INTCK() Function
- Number of Working days between two dates – INTCK() Function

**Syntax INTCK in SAS:**

**Interval –**can be in minutes, seconds, hours,weeks, days, months,quarter and year**Start_date**and**end_date**are between two dates which we will be finding interval

So we will be using **EMP_DET** Table in our example

**Difference Between two dates using INTCK function in SAS:**

difference between two dates in days, weeks, months & year in SAS using INTCK() Function is accomplished by taking ‘day’, ‘week’, ‘month’ and ‘year’ as argument respectively

data emp_det1; set emp_det; days_diff = intck('day',DOJ,curr_date); week_diff = intck('week',DOJ,curr_date); month_diff = intck('months',DOJ,curr_date); year_diff = intck('year',DOJ,curr_date); run;

So the resultant dataframe will be

**Number or working days between two dates in SAS:**

Number of working days between two dates in SAS is accomplished using** INTCK **function with** ‘weekdays’ **as argument as shown below.

/* number of working days between two dates */ data emp_det1; set emp_det; weekdays = intck('weekdays',DOJ,curr_date); run;

So the resultant dataframe will be

**Difference Between two timestamp using INTCK function in SAS:**

Difference between two timestamps in hours, minutes & seconds in SAS using INTCK() Function is accomplished by taking ‘hour’, ‘minute’ and ‘second’ as argument respectively

data emp_det1; set emp_det; hours_diff = intck('hour',last_login,curr_datetime); minutes_diff = intck('minute',last_login,curr_datetime); second_diff = intck('second',last_login,curr_datetime); run;

So the resultant dataframe will be
