Supposedly, vampires cannot go out when the sun is out during the day. Thus, they can only go out during the night.
nocturnal or kaisor or allnighter
The myth states at night they can.
They work during the day and can only make appointments at night.
Vampires rarely come out in daylight and can be found at most times during the night.
vampires go hunting at night because they sleep through the day and if they go out in the sun their skin either starts glittering or they burn xx
Vampires are typically nocturnal creatures, so they should go hunting during the night when their powers are strongest and their prey is more vulnerable. Additionally, they should choose times when there are fewer people around to witness their hunting activities to maintain their secrecy.
vampires are fake.
Vampires should hunt at night to not be seen. Vampires only hunt during hunting season. Else they would be breaking the law.
There are no vampires. (In films, or in any other fiction, they'd probably be active during the night, but avoiding any light.)
in nightlife you can have lots of cars, and you can go downtown to other lots. there are also vampires in the game and they can turn you into vampires too
In legends, vampires come out at night and sleep in their coffins during the day. They are said to drink blood.
This assumes that there is a time when vampires have to go away. Vampires always arrive late and stay to the wee hours before dawn. (Sigh) Before I continue, it might help to clarify whether we are talking about real or fictional vampires. So, with fictional vampires, the second answer is probably correct, whereas real vampires (yes, they are real - go to http://www.religioustolerance.org/vampyres) are not immobilized during daylight, nor do they "sparkle" in the sun. So, there really is no set time.
