I shave every day, but my beard stays the same. What am I?

I am not a bull but I have horns.
I am not an ass but I have a pack saddle.
Wherever I go, I leave silver behind me.

Who am I?

I am written with two letters.
I said with the one.
I usually am seen with the two.

Who am I?

What is in seasons, seconds, centuries and minutes but not in decades, years or days?

You see me once in June, twice in November, and not at all in May. What am I?

What is full of holes but still holds water?

As a whole I am both
safe and secure.

Behead me and I become
a place of meeting.

Behead me again and I am
the partner of ready.

Restore me, and I become
the domain of beasts.

What am I?

I am first found in caves, now prolific online; I am a depiction, a drawing, a symbol, or sign. I will convey whichever mood you could wish; or for that matter, a fist, flask, or fish. What am I?

Who has married many women but was never married?

I welcome the day with a show of light, I stealthily came here in the night. I bathe the earthy stuff at dawn, But by noon, alas! I'm gone.
