So, 1700s?

Year 1700 (MDCC) was an exceptional common year starting on Friday of the Gregorian calendar and a leap year starting on Monday of the Julian calendar. The Gregorian calendar was 10 days ahead of the Julian calendar until February 28, 1700, then 11 days ahead from March 1, 1700. With the Gregorian Calendar starting in 1582, and 1600 being evenly divisible by 400, and thus being a leap year under the Gregorian system despite being a century year, this was the first skipped leap year under the Gregorian Calendar.
