拂晓,又称黎明,古称昧爽,指早晨在日出之前的太阳已在地平线下6度以上,天将晓而尚暗之时段,日常定义是物体已经能够被辨识,而且户外活动也可以开始进行的时段。

航海拂晓是日出之前太阳仍在地平线下12度的时段。航海拂晓的定义是阳光仅足以辨识物体。

天文拂晓是黎明之前,太阳仍在地平线下18度的时段。天文拂晓的定义是阳光开始渗入天空的时刻,在这之前的天空仍是完全黑暗的。

拂晓不会与日出混淆,那是太阳的边缘刚刚从地平线露出来的时刻,叫做破晓。

西方的民俗学者认为这是恶魔、精灵、鬼魂和魔鬼等不祥之物,甚至撒但都会消失在曙光之中,因为这些来自黑暗的生物憎恨光线,特别是来自太阳的光,在基督徒之前的凯尔特人也有相同的信仰。

Dawn is sometimes considered the beginning of morning twilight (as depicted here), sometimes the period of twilight, and sometimes the time of sunrise.
Dawn sky in Metz, France
Serra dos Órgãos National Park, in Rio de Janeiro state, Brazil, at dawn.
Civil, nautical, and astronomical dawn, when defined as the beginning time of the corresponding twilight.[4]

Dawn (from an Old English verb dagian "to become day") is the time that marks, depending on the specific usage, the beginning of the twilight before sunrise, the period of the pre-sunrise twilight or the time of sunrise. When identified as the beginning of or the period of twilight, it is recognized by the presence of weak sunlight, while the Sun itself is still below the horizon.
