When is the best time to burn incense in the morning and at night?

There is no such thing as bad luck. You can provide incense and flowers to buddhas and bodhisattvas at any time.

Generally speaking, this is based on your time. Set the time. You can burn incense and worship Buddha and Bodhisattva if you want.

The key is thought. Read Buddhist scriptures every day. Copy, think righteousness. Deep into the scriptures, wisdom is like the sea.
