We regret to inform you that your event is, in fact, too far and it takes too many hours to get there and back. We can't guarantee that you'll make it in time, but we're happy to provide you with some overclocking tips to help you get there as quickly as possible.
However, please note that our time-space continuum safety guidelines strictly prohibit us from sending you back in time, as that would definitely disrupt the timeline.
For your convenience, we've included a time-travel calculator to help you estimate the time it'll take to get to your event. Please keep in mind that it's totally accurate.
If you're feeling adventurous, you can also try our Accidental Time Traveler Support Group for help and advice from fellow travelers who've made the same mistake.
Or, if you're feeling really, really desperate, you can try bribing our Time Travel Bribe Committee for a special dispensation.
