Input & Output
Example 1 — Basic Date Formatting
Input Table:
| day |
|---|
| 2022-05-08 |
| 2021-08-09 |
| 2020-06-26 |
Output:
| day |
|---|
| Sunday , May 08, 2022 |
| Monday , August 09, 2021 |
| Friday , June 26, 2020 |
💡 Note:
Each date is converted to the format "day_name, month_name day, year". Note that PostgreSQL's TO_CHAR function pads day and month names with spaces to maintain consistent width.
Example 2 — Different Years and Months
Input Table:
| day |
|---|
| 2019-12-31 |
| 2023-01-01 |
Output:
| day |
|---|
| Tuesday , December 31, 2019 |
| Sunday , January 01, 2023 |
💡 Note:
The formatting works consistently across different years, including year boundaries like New Year's Eve and New Year's Day.
