Nami is in multiple Harvest Moon games. The answer depends on which Harvest Moon game you are playing.
the time you wake up
First, you must buy a pond for 2,500G from Takakura. Then, during Summer of Chapter 2, wake up in the morning at a later time than your wife.
use the watering can and when it says check one the A button it will wake him up.
You can't ever die. You can pass out from exhaustion but you'll just wake up in your house.
I am sorry to say but there is no green heart event for Nami. There are Black, Purple , Blue , and Yellow. This is what they are. You probably have the black but if not on Here it is. Black- 12 pm - 2 pm On a rainy Tuesday in the Inner Inn lobby you ring the bell alot. Then Nami will come. Tell her you will stay the night. Purple- 6 am- 12 pm In the Inner Inn lobby On a rainy Tuesday Nami will come out. Then she asks you about farm life. You teach her about milking and brushing. Blue- When you just wake up you hear a knock on the door. You tell them to come in. It turns out to be Nami. You say I'll take care of it and pick a choice. Yellow- Exit farm house from 6 am- 12 pm On a sunny day you tell her No Problem. Hope this helped.
It happens at night. But when you wake up that day you automatically go to the wedding. The day ends as soon as the wedding finishes. So it is impossible to see exactly what time the ceremony takes place.
To get the island on Harvest Moon, you have to have one billion G (1000000000G). This can easily be done by employing members of the fishing team to fish for you in the Winter Season. Once you have the money, you will wake up one morning, exit your house and Thomas will meet you and offer you the island.
You need to have Chen or Charlie at 3 hearts. Then you will wake up one morning and they will present it to you.
if your friendship is high enough, the trapdoor will always be open. if you want to talk to daryl when hes not in the basement go as soon as you wake up :D xx

To get the horse on harvest moon, you have to just continue your farming life and then one morning when you wake up theres a knock at the door and Takakura says that he found a horse running around the village, and then he gives it to you because nobody knows who he belongs to. I'm not entirely sure when this happens but I think it happens sometime in year 2.
When the season hits summer and you wake up Nak,Nic, and Flak will tell you to come where they are and Nic and Nak will be fighting over it then they give it to you.
