+# Extract and Convert Date in a Text or String to GlideDate Format
+
+## Use Case / Requirement
+This script extracts a date from a string formatted as "20 Nov 2020" and converts it into the GlideDate format used in ServiceNow. This is particularly useful for maintaining accurate records of software patches and updates.
+
+## Solution
+The solution utilizes the `GlideDate` object to parse the date from the string and format it appropriately. The script extracts the day, month, and year, then constructs a formatted date string.
+
+## Example Input and Output
+- **Input Format**: Example string containing patch information
+  - Example: `"kernel-headers-2.6.32-754.35.1.el6.x86_64 20 Nov 2020"`
+- **Output Format**: 
+  - GlideDate format: `2020-11-20` (if displayed in `yyyy-MM-dd` format)
+
+## Code Snippet
+Please find the attached javascript file to know how to implement it. Thank you!
