I want to create a time series field between two dates where day is not mentioned, only month and year is mentioned.
First of all: never use two-digit years. After the Y2K scare, this should be an absolute given for anybody involved in the IT business.
SAS Tutorials: Date-Time Functions and Variables in SAS
Second, don't use date formats in a non-hierarchical order MY in your case. Start with the most significant part years. This helps in ordering when formatted values are used. Third, use SAS date values when dates are involved. View solution in original post. Need further help from the community? Please ask a new question. Tell us what you think about SAS technology.

I have added 'how to read this format' in the post. Hope it helps! How to use datetime with format? A small program example will be of great help. Hiyou can do this by using format varname monname. Why used 6 and 15 in the below statment. INPUT 6 date1 ddmmyy8. Hello Deepanshu as we have different dates in one format using anydtdte. Hi, I think your data step is incorrect.
This tutorial describes the usage of SAS Date formats and informats. It includes practical real-world data problems related to SAS formats. It is also used when you create a new variable in a dataset. Let's understand by examples. It creates a dataset called sampledata which is stored in WORK library. In this case, 8 and 10 refers to width of the date. It is not meaningful if you look at the value.
You cannot tell which date it is. Result : It returns as 30DEC is the today's date. The PUT statement is used to show value in log window. To display date in WORD format.

Unknown 8 April at Deepanshu Bhalla 8 April at Anonymous 3 September at Anonymous 10 November at Unknown 14 November at Karan 17 November at The legal and cultural expectations for date and time representation vary between countries, and it is important to be aware of the forms of all-numeric calendar dates used in a particular country to know what date is intended.
Many countries have adopted it as their sole official date format, though even in these areas writers may adopt abbreviated formats that are no longer recommended. For English speakers, MDY was preferred form mmm-dd-yyyy Example: April 9, and used by nearly all English language publications and media companies as well as majority of English language government documents.

The day is also written with Arabic numerals.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. Note that there are only two different variable types in SAS - character and numeric. Dates are stored in numeric variables and are generally formatted to appear as user-readable dates. Specifically, dates are stored as the number of days since 01JAN So if you have a number already formatted as a date, and would like it to appear formatted differently but still be a number you simply need to change the format.
As Joe's comment says - I can't see the relationship between the date you provided and the number you desire maybe you have a typo?
But the below piece of code will demonstrate how you can simply change the format to change the appearance of the number:.
If you want an explicit numeric value, you can use the date functions on your date variable which, as pointed out, is a numeric date value SAS understands. Disclaimer being I'd reccomend just formatting whatever else you have properly, so you don't need to represent the date as a number. If you're looking to add or substract increments of dates, you might want to look at the intx function too.3.8 Handling dates in R

For example, ? Your general idea is right, but I have to -1 because of the unnecessary character-numeric conversion warning.
Use input instead of That will concatenate, trim, and do the conversion for you. Pipe symbols for concatenation should rarely be used these days. I need instead of I tried three methods, all give me This doesn't do what it needs to.
You are input ing an already numeric value incorrectly. I find this answer very confusing. I think this is more likely to confuse anyone asking this type of question than to help them. I am confused and the code run through, but it generate a new data set with two columns and 1 obs.

Date Formats let you display date columns in your output data-set based on your preference for date form. It is common for people to confuse formats and informats. The former controls how your date columns are displayed or printed, while the latter tells SAS the date form used in the input data-set, so SAS can import it properly. If you want to display a date in this form:. First, it is important to realize that for this particular format, the default separator or delimiter is a dash or hyphen.
The slash is one of the other possible separators you can use. Here are the others:. Since in our example we are using a slash, the code below is how you would code it. The 10 represents the width of the output field. If you count how many characters make up that date format, you will notice that it is This is a very common date format as well that will let you write date values in these forms:. The default width of the output field is 7, and the range is 5 to For example:. If you are confused by this syntax, please check out my article on the put and input functions link to it belowand if you still have questions, please ask me on here!
The SAS mdy function has three required arguments. Not surprisingly, the function takes in the month, day, and year, and in that order. If you have some knowledge about how dates are handled in SAS, you know that the date in the form we expect it to be in, would not be stored in the dateofhire variable. Instead, a number representing the date in this case,would be stored.
For example, you could use worddate. Your email address will not be published. Skip to content. Start Now! How would you accomplish this? Here are the others: n no separator b blank d dash s slash p period c colon Since in our example we are using a slash, the code below is how you would code it.

If you'd like to download the sample dataset to work through the examples, choose one of the files below:. Dates, times, and date-times are commonly used variable types in research. In SAS, dates and times are considered numeric variables, but they have several special properties to be aware of.
Regardless of how the researcher records dates or times in their dataset, SAS "internally" records datetime variables as integers.
SAS Date Formats and Informats
This helps to simplify the computations when computing the differences between dates. By default, SAS date and time variables are printed using the SAS internal values, rather than a "human-readable" date format. However, dates can be displayed using any chosen format by setting the format in a data step or proc step. In this tutorial, we show how to compute new variables from dates and times using two major types of date functions: extraction-type functions and computation-type functions.
Date extraction functions are used to extract a portion of a date from a date variable. Date creation functions construct new date or datetime variables based on their inputs. Date computation or "date difference" functions carry out arithmetic operations on dates; for example, computing the elapsed time between two dates.
The basis argument determines how the date arithmetic is carried out. Specifically, it determines the number of days that should be used to characterize the period of time in a month or year. In SAS 9.
Here the QTR function extracts the quarter value from the date value variable DOB and saves it in the new numeric variable quarter. Here the DAY function extracts the day value from the date variable DOB and saves it in the new numeric variable days. Here a new variable date will be created by combining the values in the variables mndaysand yr using the MDY function.

SAS date values are the stored internally as the number of days between January 1,and a specified date. Dates after January 1,are stored as positive numbers; dates before January 1,are stored as negative numbers. Table 1: SAS internal values for selected dates. YEAR - Given a number or a variable representing a date or datetime, returns the year.

SAS stores dates as the number of days sinceso a date value is a specific day. If you want all dates in the same month to appear the same then apply a date format that only displays the month and year MONYYw. If you want all dates in the same month to be transformed to the same date then use the INTNX function. You can use the format in a proc sql statement. I think the format you want is Learn more.
