Often used in daily conversation to refer to the early part of the day. Can be modified with time expressions (e.g., 今天早上, 明天早上).
'早上' is the early part of the morning (from sunrise to around 9 AM), while '上午' refers to late morning (9 AM to noon). For example, '早上六点' means 6 AM, but '上午九点' means 9 AM.
Composed of '早' (early) and '上' (top/beginning), indicating the early part of the day.
'早上' is more colloquial than '早晨' (which sounds more formal or literary). '上午' refers to late morning (roughly 9 AM to noon), while '早上' covers the entire morning period.
