It's time for some real talk. There seems to be some confusion/autism about the appropriate time to employ active dread. One dude actually posted a thread here talking about "whoa guys, watch out for the Second Date Shit Test" because chicks would ghost him once he contacted them after ignoring them. (If you don't know the difference between active and passive dread, the sidebar is that way ------>)
 
TRP and AskTRP are both full of lads who are proudly reporting about their first date, usually involving a k-close or heavy makeout/petting session and now they're wondering where to go from there, after which someone will commonly respond along the lines of "ignore this bitch for the next 28-75 hours (but no more than 83.5 in a leap year) and then text her with a time and place that you're gonna fuck for sure this time".
 
[trump]Wrooooong[/trump] Dread is rarely your friend until after you've fucked her. Your dick is the drug, but you can't get her hooked on it until you've actually put the thing inside her. Active dread is for maintaining/re-establishing frame and/or influencing her behavior after you've already shown her how good your dick is.
 
IT'S OK TO SHOW SOME INTEREST at this point. Now, I'm not advocating for gushing to her about how much fun you had 30 seconds after you leave each other and beg for a second date, but ignoring a woman you dated but haven't fucked yet is f-close suicide. Why? The hamster goes into spacetime-splitting overdrive on that wheel, wondering what the fuck went wrong. "I thought we had a nice time, but it's been two days and I haven't heard from him...." This is going on the entire time you're sitting there all smug, thinking about how alpha you are for making this bitch wait for more kisses.
 
Meanwhile, your self-inflicted blackout period ends and you text or call to set up this next "guaranteed" date and after DAYS of hamstering by herself and with her friends, she immediately either assumes that you're gaming her (only betas play games) or that you were so uninterested that you couldn't even be bothered to contact her. Either way, you've either ended all chances of seeing her again or you've just made the road to f-town a lot more challenging by making ASD seem like her only option going forward. Remember gents: they hate the game, not the player. I'm sure a lot of the lemmings here are saying "but bro now she knows that I'm soooo busy with my super fulfilling life that I didn't have time to even think about her" as if that's a good thing at this point. News flash: she only cares about her and how you made her FEEL and ignoring her makes her feel shitty because you haven't given her anything to make her feel good (AKA your dick).
 
So, what should you do instead? If you are still hung up on letting this girl know you're gasp interested in her by texting/calling the next day, set up the second date before you even leave.

Hey I had fun. I'd like to see you again. There's a kickass band that I'm seeing at O'Doyle's on Friday. Let's go see it"

and then text her when the time is right for the appropriate logistics.
 
Or, tell her that you'd like to meet up again, but you're not sure when you're available. Maybe ask her when she's available later on, then say "cool. I'll hit you up later when I know more about when I'm free" and then actually do that. Do whatever you think is best as long as it doesn't involve some stupid Brady Bill-esque waiting period. STRIKE WHILE THE IRON IS HOT or spend more time trying to heat it up again after you've dumped water all over it by ignoring her.
 
Summary: employing active dread before you fuck a woman is counterproductive to your goals, unless you like ASD, hamsters and not getting laid.
