We can use the INTNX function to create a new column called firstmonth that contains the first day of the month for each date in the date column: /*create new dataset with column that contains first day of the month*/ data new_data; set original_data; firstmonth=intnx('month', date, 0); format. The number-of-the-week value is represented as a decimal number in the range 0–53, with a leading zero and maximum value of 53. INTCK can give results that aren't what you want in all cases, as it counts from the beginning of the interval (see the Details section of the documentation). Syntax. I believe this happens because the alignment option in the INTCK function defaults to DISCRETE, which counts interval boundaries in between two dates, rather than CONTINUOUS, which counts full intervals in between dates, shifted to the start date. Basically, we had to apply one of two formulas to compute variable right_hours_slept: (wake_time-bed_time)/3600 if bed_time is "at or after midnight. INTNEST Function. SAS INNOVATE 2024.
