Daylight Saving Time ends in Europe on October 31

This Sunday, October 31st, will mark the end of daylight saving time (DST) for countries in Europe (except Iceland). At 3AM, you turn your clock back 1 hour to 2AM. In the short term, everyone gets an extra hour of sleep.

In the medium term, for the next week, until Sunday, November 7th, the U.S. and Europe will be separated by five hours -- one less hour than normal. For example, 9am New York will be 2pm Zurich, Switzerland. This means that US filers will have one extra hour to submit their documents to European-based agencies. For example, US filers will now have until 7pm ET to submit their documents to WIPO in Switzerland to receive the same-day filing date.
