# Register on Birthday

Normally, birthday campaigns do not trigger if a member is registered on his birthday. There is a way to create such a campaign using the following expression in conditions:

```
customer.birthDate.format("d-m") === event.eventDate.format("d-m")
```

This way, a reward will be given to the members who registered on their birthday. To give rewards to other members on their birthdays, you still have to create a regular birthday campaign.
