Year references would be nice to match

[dschmitt007]

It would be nice to get a range to know that references like:

40s, 1943, early mid 20th century, Meji Period
are all contemporary. It would be nice to include more dates/events :

e.g. everything under:

https://en.wikipedia.org/wiki/Japanese_calendar
https://en.wikipedia.org/wiki/Chinese_calendar
https://en.wikipedia.org/wiki/Celestial_stem
https://en.wikipedia.org/wiki/Islamic_calendar
https://www.rca.org/resources/liturgy-rca-basics-worship/liturgical-calendar
https://en.wikipedia.org/wiki/Buddhist_calendar
https://pastafarians.org.au/pastafarianism/holidays

Double bonus would recognize major cultural time references (maybe crawl wikipedia to generate big list of named times):

baby boom, end of world war 2, great depression, dark ages, renaissance, little ice age, age of exploration

More astrological references:
equinox
lunar eclipse
solar eclipse
mercury in retrograde

Boxing day
