One will use SAS code like: age_months = floor ( (intck ('month',birthdate,vacine_date)- (day (vacine_date) < day (birthdate)))); Here's a sample program showing how to use it:I am guessing, but it seems as if your variable letter_date is not an actual SAS date value, it is some integer that looks like a date to humans but does not look like a date to SAS. They can be used for calendar calculations with SAS date values, to count time intervals between dates, and to increment dates or datetime values by intervals. means a SAS interval name, plus an optional multiplier and/or shift index. You would not need to use the intck function to tell the days differnce, just use subtraction. can determine the frequency for all days of the week between start and end dates. The WEEK function with the W descriptor reads a SAS date value and returns the number of the week within the year. The syntax is very similar to the INTNX function, INTCK(interval, from, increment, alignment). You need to apply a format to the date value so it displays properly. ちなみに同じ結果を返す他の計算式として、以下2つ. id starttime endtime 1 2021-10-27 10:11:01 2021-10-27 10:19:33 I know intck function can do it but all the examples I.

Re: How to extract a timestamp with one hour interval. The SAS intck function computes the date and time intervals for the two different dates, while the INTCK function varies on the time units. For example, if the login recorded at the hospital is at the minutes level, which would correspond to most sign-ins I've done at a clinic, then INTCK(HOURS. You need to apply a format to the date value so it displays properly. These two functions complement each other: INTCK computes the difference between two dates, while INTNX enables you to add time units to a date value. CONCLUSION Using SAS Base’s INTCK function, one can write efficient codes to determine the frequency of the days of the week between two time intervals as illustrated with a real time example in this paper. Method 1: Age = INTCK ('year',dob,graduationdate,"C") Method 2: Age= (graduationdate-dob)/365. Desired result is the SURV_MM and N_MONTH is what I ended up with INTCK function as coded below.
