Is there a single generic term to refer, either collectively or arbitrarily, to both sunrises and sunsets?
I'm looking for something that could be used in the same vein as twilight can be used (formally or informally) to refer to both the pre-sunrise dawn period and the post-sunset dusk period, without specifying which.
I'm aware of the concept of a golden hour within the photography and cinematography communities, but I'm looking for something which refers more to the specific astronomical event, as a particular instant in time, while still being agnostic to the direction the sun is going.
Edit: To clarify, I'd like something that could describe, even informally, any or all of:
- Instants when the sun is exactly at the horizon, or 0°,
- Periods when the sun is near the horizon on either side, e.g., –2° to +2°, or
- Periods when the sun is near the horizon, but strictly above it, e.g., 0° to +2°.
I am aware of the various astronomical definitions of twilight, but unfortunately none of them meets any of these.
