Is "先" an auto-antonym?

So apparently the [kanji meaning](https://www.wanikani.com/kanji/%E5%85%88) of
this word is "previous" or " **past** ". This seems to be tied to the Chinese
origin and its on'yomi reading (せん), maybe?

The [vocabulary meaning](https://www.wanikani.com/vocabulary/%E5%85%88) of the
standalone word is "ahead" or " **future** ". This meaning may be connected to
the Japanese influence on the word and its kun'yomi reading (さき).

_Is it true that this kanji (先) can refer to both future events and past ones?
How did it evolve to be this way and what has the original chinese meaning to
do with it?_

**UPDATE:** So, this kanji means "prior" or "first" in Chinese according to
this [source](https://www.purpleculture.net/dictionary-
details/?word=%E5%85%88). This further validates that it originally was
connected to the concept of "past" and the "future" meaning came later and was
introduced solely in Japan.

This still does not fully answer any questions.

Also my question are tangentially related to this
[exchange](https://japanese.stackexchange.com/questions/16017/i-am-struggling-
with-the-sometimes-conflicting-uses-of-%E5%85%88?rq=1). But my questions have
not been satisfactorily answered by that question and the core differs from
what I am interested in.




The Japanese word さき means the tip of something. For example, 指先 is the tip of
a finger. When it is written as 崎, it means a cape, the tip of a land facing
the sea.

When it refers to space, 先 means something like "ahead" or "a little farther"
with respect to some reference point. It is usually modified by something that
comes before it, as in この先, コンビニの先, etc. Imagine an arrow pointing towards
that direction. It should not be difficult to see the connection with "tip."

When it refers to time, 先 basically means "earlier," not necessarily the past.
This meaning is consistent with Chinese.

> 先に行くね。  
>  _先走了。_

The noun-modifying form 先の, as in 先の戦争 in reference to WWII, has a formal tone
to it. Incidentally, its pitch accent is [さきの]【HLL】, not [さきの]【LHH】 as in the
other senses.

先 does refer to a future time in certain expressions, as in 三年先, 先が思いやられる,
etc. This can be understood as an analogical usage of the spatial sense. You
are heading towards the future, after all. In fact, この先 can be used in both
senses. This usage of 先 seems mostly limited to contexts where you want to
emphasis remoteness or uncertainty. If you want to state some concrete event
is planned to happen in three years, you would most likely say 三年後, not 三年先.

To me, the English expressions “push back” and “push forward” are far more
confusing. I am biased, of course.
