What a great date and time for a launch event: 11/11/11.

To be even fancier, and precise… schedule it at 11:11 am (and 11 seconds). You could launch at night at 11 pm, however, 11 pm is technically 23:00 not 11:00.

To be honest, it probably looks more interesting than your target audience is really interested. If you have a big enough fan base, with enough enthusiasm for your upcoming product, they’ll remember any date you set.
