# Date & Time Format Directives

These directives are commonly used in tools like `date`, logging systems, and programming languages to format timestamps.

## Directives

| Directive | Represents            | Example |
| :-------- | :-------------------- | :------ |
| `%Y`      | 4-digit year          | `2026`  |
| `%m`      | Month                 | `01-12` |
| `%d`      | Day of month          | `01-31` |
| `%H`      | Hour (24-hour format) | `00-23` |
| `%M`      | Minute                | `00-59` |
| `%S`      | Second                | `00-59` |
