| | `%d` | `08` | Day number (01--31), zero-padded to 2 digits. | |
| | `%e` | ` 8` | Same as `%d` but space-padded. Same as `%_d`. | |
| | | | | |
| | `%a` | `Sun` | Abbreviated weekday name. Always 3 letters. | |
| | `%A` | `Sunday` | Full weekday name. Also accepts corresponding abbreviation in parsing. | |
| | `%w` | `0` | Sunday = 0, Monday = 1, ..., Saturday = 6. | |
| | `%u` | `7` | Monday = 1, Tuesday = 2, ..., Sunday = 7. (ISO 8601) | |
| | | | | |
| | `%U` | `28` | Week number starting with Sunday (00--53), zero-padded to 2 digits. [^2] | |
| | `%W` | `27` | Same as `%U`, but week 1 starts with the first Monday in that year instead.| |
| | | | | |
| | `%G` | `2001` | Same as `%Y` but uses the year number in ISO 8601 week date. [^3] | |
| | `%g` | `01` | Same as `%y` but uses the year number in ISO 8601 week date. [^3] | |
| | `%V` | `27` | Same as `%U` but uses the week number in ISO 8601 week date (01--53). [^3] | |
| | | | | |

| | `%F` | `2001-07-08` | Year-month-day format (ISO 8601). Same as `%Y-%m-%d`. | |
| | `%v` | ` 8-Jul-2001` | Day-month-year format. Same as `%e-%b-%Y`. | |
| | | | | |
| | | | **TIME SPECIFIERS:** | |
| | `%H` | `00` | Hour number (00--23), zero-padded to 2 digits. | |
| | `%k` | ` 0` | Same as `%H` but space-padded. Same as `%_H`. | |
| | `%I` | `12` | Hour number in 12-hour clocks (01--12), zero-padded to 2 digits. | |
| | `%l` | `12` | Same as `%I` but space-padded. Same as `%_I`. | |
| | | | | |
| | `%P` | `am` | `am` or `pm` in 12-hour clocks. | |
| | `%p` | `AM` | `AM` or `PM` in 12-hour clocks. | |

| | `%f` | `026490000` | The fractional seconds (in nanoseconds) since last whole second. [^7] | |
| | `%.f` | `.026490`| Similar to `.%f` but left-aligned. These all consume the leading dot. [^7] | |
| | `%.3f`| `.026` | Similar to `.%f` but left-aligned but fixed to a length of 3. [^7] | |
| | `%.6f`| `.026490` | Similar to `.%f` but left-aligned but fixed to a length of 6. [^7] | |
| | `%.9f`| `.026490000` | Similar to `.%f` but left-aligned but fixed to a length of 9. [^7] | |
| | `%3f` | `026` | Similar to `%.3f` but without the leading dot. [^7] | |

| | `%r` | `12:34:60 AM` | Hour-minute-second format in 12-hour clocks. Same as `%I:%M:%S %p`. | |
| | | | | |
| | | | **TIME ZONE SPECIFIERS:** | |
| | `%Z` | `ACST` | Local time zone name. Skips all non-whitespace characters during parsing. Identical to `%:z` when formatting. [^8] | |
| | `%z` | `+0930` | Offset from the local time to UTC (with UTC being `+0000`). | |
| | `%:z` | `+09:30` | Same as `%z` but with a colon. | |
| |`%::z`|`+09:30:00`| Offset from the local time to UTC with seconds. | |
| |`%:::z`| `+09` | Offset from the local time to UTC without minutes. | |
| | `%#z` | `+09` | *Parsing only:* Same as `%z` but allows minutes to be missing or present. | |
| | | | | |
| | | | **DATE & TIME SPECIFIERS:** | |
| |`%c`|`Sun Jul 8 00:34:60 2001`|Locale's date and time (e.g., Thu Mar 3 23:05:25 2005). | |
| | `%+` | `2001-07-08T00:34:60.026490+09:30` | ISO 8601 / RFC 3339 date & time format. [^5] | |
| | | | | |
| | `%s` | `994518299` | UNIX timestamp, the number of seconds since 1970-01-01 00:00 UTC. [^6]| |
| | | | | |
| | | | **SPECIAL SPECIFIERS:** | |
| | `%t` | | Literal tab (`\t`). | |
| | `%n` | | Literal newline (`\n`). | |
| | `%%` | | Literal percent sign. | |
| |
| It is possible to override the default padding behavior of numeric specifiers `%?`. |
| This is not allowed for other specifiers and will result in the `BAD_FORMAT` error. |
| |
| Modifier | Description |
| -------- | ----------- |
| `%-?` | Suppresses any padding including spaces and zeroes. (e.g. `%j` = `012`, `%-j` = `12`) |
| `%_?` | Uses spaces as a padding. (e.g. `%j` = `012`, `%_j` = ` 12`) |
| `%0?` | Uses zeroes as a padding. (e.g. `%e` = ` 9`, `%0e` = `09`) |
| |
| Notes: |
| |
| [^1]: `%C`, `%y`: |
| This is floor division, so 100 BCE (year number -99) will print `-1` and `99` respectively. |
| |
| [^2]: `%U`: |
| Week 1 starts with the first Sunday in that year. |
| It is possible to have week 0 for days before the first Sunday. |
| |
| [^3]: `%G`, `%g`, `%V`: |
| Week 1 is the first week with at least 4 days in that year. |
| Week 0 does not exist, so this should be used with `%G` or `%g`. |
| |
| [^4]: `%S`: |
| It accounts for leap seconds, so `60` is possible. |
| |
| [^5]: `%+`: Same as `%Y-%m-%dT%H:%M:%S%.f%:z`, i.e. 0, 3, 6 or 9 fractional |
| digits for seconds and colons in the time zone offset. |
| <br> |
| <br> |
| This format also supports having a `Z` or `UTC` in place of `%:z`. They |
| are equivalent to `+00:00`. |
| <br> |
| <br> |
| Note that all `T`, `Z`, and `UTC` are parsed case-insensitively. |
| <br> |
| <br> |
| The typical `strftime` implementations have different (and locale-dependent) |
| formats for this specifier. While Chrono's format for `%+` is far more |
| stable, it is best to avoid this specifier if you want to control the exact |
| output. |
| |
| [^6]: `%s`: |
| This is not padded and can be negative. |
| For the purpose of Chrono, it only accounts for non-leap seconds |
| so it slightly differs from ISO C `strftime` behavior. |
| |
| [^7]: `%f`, `%.f`, `%.3f`, `%.6f`, `%.9f`, `%3f`, `%6f`, `%9f`: |
| <br> |
| The default `%f` is right-aligned and always zero-padded to 9 digits |
| for the compatibility with glibc and others, |
| so it always counts the number of nanoseconds since the last whole second. |
| E.g. 7ms after the last second will print `007000000`, |
| and parsing `7000000` will yield the same. |
| <br> |
| <br> |
| The variant `%.f` is left-aligned and print 0, 3, 6 or 9 fractional digits |
| according to the precision. |
| E.g. 70ms after the last second under `%.f` will print `.070` (note: not `.07`), |
| and parsing `.07`, `.070000` etc. will yield the same. |
| Note that they can print or read nothing if the fractional part is zero or |
| the next character is not `.`. |
| <br> |
| <br> |
| The variant `%.3f`, `%.6f` and `%.9f` are left-aligned and print 3, 6 or 9 fractional digits |
| according to the number preceding `f`. |
| E.g. 70ms after the last second under `%.3f` will print `.070` (note: not `.07`), |
| and parsing `.07`, `.070000` etc. will yield the same. |
| Note that they can read nothing if the fractional part is zero or |
| the next character is not `.` however will print with the specified length. |
| <br> |
| <br> |
| The variant `%3f`, `%6f` and `%9f` are left-aligned and print 3, 6 or 9 fractional digits |
| according to the number preceding `f`, but without the leading dot. |
| E.g. 70ms after the last second under `%3f` will print `070` (note: not `07`), |
| and parsing `07`, `070000` etc. will yield the same. |
| Note that they can read nothing if the fractional part is zero. |
| |
| [^8]: `%Z`: |
| Since `chrono` is not aware of timezones beyond their offsets, this specifier |
| **only prints the offset** when used for formatting. The timezone abbreviation |
| will NOT be printed. See [this issue](https://github.com/chronotope/chrono/issues/960) |
| for more information. |
| <br> |
| <br> |
| Offset will not be populated from the parsed data, nor will it be validated. |
| Timezone is completely ignored. Similar to the glibc `strptime` treatment of |
| this format code. |
| <br> |
| <br> |
| It is not possible to reliably convert from an abbreviation to an offset, |
| for example CDT can mean either Central Daylight Time (North America) or |
| China Daylight Time. |
