不，英文中日期的缩写不是按照数字直接加上“th”来表示的。英文日期的缩写需要根据具体的日期来决定结尾的字母。以下是英文中1到31日正确的缩写形式：
- 1st - 1st January
- 2nd - 2nd January
- 3rd - 3rd January
- 4th - 4th January
- 5th - 5th January
- 6th - 6th January
- 7th - 7th January
- 8th - 8th January
- 9th - 9th January
- 10th - 10th January
- 11th - 11th January
- 12th - 12th January
- 13th - 13th January
- 14th - 14th January
- 15th - 15th January
- 16th - 16th January
- 17th - 17th January
- 18th - 18th January
- 19th - 19th January
- 20th - 20th January
- 21st - 21st January
- 22nd - 22nd January
- 23rd - 23rd January
- 24th - 24th January
- 25th - 25th January
- 26th - 26th January
- 27th - 27th January
- 28th - 28th January
- 29th - 29th January
- 30th - 30th January
- 31st - 31st January
因此，22日的正确缩写是 "22nd"。需要注意的是，当数字大于20时，通常只有20th、21st、22nd、23rd这几个日期的缩写会加上特定的后缀，其他以0结尾的日期（如30th）也使用“th”。
