Date notation regular expression

I thought about regular expressions that are conscious of Japanese date and time notation and American date and time notation. There may be a bug, but a memorandum. It's a little unreasonable for the English-style day-month-year format, but I haven't seen it. In the last year, month, day, hour, minute, and second, I was able to hit the python regular expression for the time being. Why is it so troublesome? ..

Regular expression that hits day

'\\s*(?:[12][0-9]|3[01]|0?[1-9])\\s*?(?:th\\s*)?[Day\\-/\\.,]?'

Regular expression that hits the month

'\\s*(?:(?:1[0-2]|0?[1-9])\\s*?[Moon\\-/\\.,]?|(?:Jan(?:uary|\\.)?|Feb(?:ruary|\\.)?|Mar(?:ch|\\.)?|Apr(?:il|\\.)?|May\\.?|Jun[e|\\.]?|Jul[y|\\.]?|Aug(?:ust|\\.)?|Sep(?:tember|\\.)?|Oct(?:ober|\\.)?|Nov(?:ember|\\.)?|Dec(?:ember|\\.)?)\\s*)'

Regular expression that hits the year

'\s*(?:\d{4}|[\']?\d{2})\s*[Year\-/\.,]?'

Regular expression that hits the first year of the Japanese calendar (gengo)

From Taika to Reiwa

Regular expression that hits the hour

'\\s*(?:1[0-9]|2[0-4]||0?[0-9])\\s*?[\\.:Time]?'

Regular expression that hits the minute

'\\s*(?:[1-5][0-9]|0?[0-9])\\s*?[\\.:Minutes]?'

Regular expression that hits seconds

'\\s*(?:[1-5][0-9]|0?[0-9])\\s*?(?:Seconds|[Ss]ec(?:onds)?)?'

Regular expression that hits the day of the week

'\\s*(?:\\(?[Sunday Monday Tuesday Wednesday Thursday Friday Saturday](?:Dayoftheweek)?\\)?|(?:Sun|Mon|Tues?|Wed(?:nes)?|Thu(?:rs)?|Fri|Sat(?:ur))(?:day)?[\\.,]?)'
