| L | Whether it's a leap year | 1 if it is a leap year, 0 otherwise. |
| o | ISO-8601 week-numbering year. This has the same value as Y, except that if the ISO week number (W) belongs to the previous or next year, that year is used instead. Since PHP 5.1.0 |
Examples: 1999 or 2018 |
| Y | A full numeric representation of a year, 4 digits | Examples: 1999 or 2018 |
| y | A two digit representation of a year | Examples: 99 or 18 |
| Time | ||
| a | Lowercase Ante meridiem and Post meridiem | am or pm |

Example: 654321 |
| v | Milliseconds - Since PHP 7.0.0. Same note applies as for u. |
Example: 654 |
