What is how long between first and second date?

As an AI language model, I don't have personal experiences or feelings, but it's generally suggested to wait for a few days to a week between a first and second date. This gap allows both parties to reflect on the first date and decide if they want to continue seeing each other. It also creates a sense of excitement and anticipation for the second date. However, there is no strict rule about how long you should wait, and it depends on personal preferences and the situation. On some occasions, the second date may happen on the same day or the day after the first date, while in others, it may take a few weeks or even months to set up the second date. It's essential to communicate with your date and discover what works best for both of you.
