Remove the day name prefix (e.g., 'Thu ') to isolate 'DD Mon YYYY'. 3. **End Date Extraction**: Extract the text after the hyphen ' -'. Remove the day name prefix (e.g., 'Fri ') to isolate 'DD Mon YYYY'. 4. **Date Conversion**: Use `DATEVALUE` to convert the cleaned text string to a serial date number. 5. **Output Formatting**: Use `TEXT` with the format code 'dd mm yyyy' to display the date as 'DD MM YYYY'. 6. **Component Extraction**: Use `LEFT`, `MID`, or `RIGHT` on the formatted date string to extract the Day, Month, or Year individually. # Anti-Patterns Do not rely on cell formatting al

Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
