strftime

strftime (short for 'string format time') is a function and formatting standard used in programming languages to convert date and time objects into human-readable strings based on specified patterns. It allows developers to customize the output format of dates and times, such as displaying '2023-10-05' or 'Thursday, October 5, 2023'. This concept is widely implemented in languages like C, Python, Ruby, and PHP for date-time manipulation and display.

Also known as: strftime patterns, time formatting, date formatting, strftime format, strftime specifiers

Why learn strftime?

Developers should learn strftime patterns when they need to format dates and times for user interfaces, logging, data serialization, or localization in applications. It is essential for tasks like generating timestamps in reports, displaying dates in web applications, or parsing time data in a consistent format across different systems, as it provides a flexible and standardized way to handle date-time representations.
