How to Convert Date Format in React Native without Intl: A Guide for Android Developers
When working with date formats in React Native, especially on Android, developers often encounter certain obstacles. One common scenario arises when you need to convert a date represented as a string (like 202001) into a more readable format, such as January_2020. While many developers turn to the Intl object for formatting dates, it may not always work as expected in Android environments, leading to errors like "can't find variable: Intl".
In this guide, we will break down a solution that utilizes the Date class instead—offering compatibility across platforms, including both Android and iOS.
Problem Statement
Imagine you receive a date string in the format YYYYMM, such as 202001. Your goal is to convert this into a more human-friendly format that includes the full month name followed by the year, ideally looking like January_2020.
This conversion might seem straightforward, and it would be if the native Intl.DateTimeFormat was supported consistently across all platforms. However, Android can throw a wrench into these plans, as you may find yourself facing issues with this method.
Solution Overview
Instead of using Intl.DateTimeFormat, we can leverage JavaScript's built-in Date class that is accessible on both iOS and Android. This approach is lightweight and requires no additional libraries.
Step-by-Step Solution
Here's a step-by-step guide on how to achieve this conversion:
Check the Input Format: Ensure that the input string has the correct length of 6 characters, which corresponds to the YYYYMM format.
Extract Year and Month: Use a regular expression to parse the year and month from the input string.
Validate Month: Make sure the month is a valid number (between 1 and 12).
Create a Date Object: Utilize the Date constructor to create a date object with the month set accordingly.
Format the Month Name: Use the toLocaleString method to get the full month name.
Return Combined String: Format the output as ${monthName}_${year}.
The Code Implementation
Here is the implementation based on the steps outlined:

Conclusion
In summary, converting date formats in React Native does not have to be a daunting task, even when working on Android. By using the Date class and avoiding the pitfalls of Intl, you can create a robust function that works seamlessly across platforms.
Whether you are developing a new feature or troubleshooting existing code, this solution will help you cleanly convert YYYYMM strings into the desired format without additional complexity.
Feel free to test the provided code in your next React Native project, and enjoy a smoother development experience!
