How many points per heart?

Does anyone know how many points you need to get to the next heart? I kinda want to try and calculate how many times I need to give gifts to people for the next heart.

Solution 1:

According to the Wiki:

Each heart is 250 friendship points.

You can gain friendship points by:

• talking to villagers (+10 if the villager is in the middle of a special animation, like exercising or using a camera, otherwise +20; can only score once per day)
• Completing a delivery quest for them (+150);
• giving them a gift they like (see Gifts)
• making certain choices in their heart events.

You can lose friendship points by:

• not talking to a villager (-2/day);
• giving them a gift they dislike (see Gifts);
• hitting them with the slingshot;
• rummaging through a trash can when they're nearby (-25, except Linus who doesn't mind).
