Dates and Times in R

Steven Sanderson talks dates and times. First up is an overview of how built-in date functionality works in R:

In this post, we will cover the basics of handling dates and times in R using the as.Date, as.POSIXct, and as.POSIXlt functions. We will use the example code below to explain each line in simple terms. Let’s get started!

The second post covers the Date type, as well as date plus time:

In the first part of our code, we use the as.Date() function to find the next Mother’s Day. Since we don’t need to consider specific times, we can simply use the Date class, which simplifies the process. We create a vector with two elements: startMothersDay and endMothersDay, both set to “2024-05-14”. This represents the range of Mother’s Day for the year 2024. Finally, we store the result in the variable NextMothersDay and print it to the console. Voilà! We have the next Mother’s Day date.

Note that this isn’t a post about date calculation, such as finding the Nth Sunday in the month of May
