If we ignore the fractional block 781 dot 614, you're about 3 weeks off. That leaves you 17 days to petition a worldwide extension of February this year, and reducing March by the same number of weeks. It would be a nice tribute to the month February. It's always the shortest one, and could once and for all make up for it!
It's not even totally unprecedented to significantly change the date, try to set your time machine to September 8, 1752. You'll disappear into The Void! You may or may not cause riots by messing with people's calendar, so do this at your own risk.
