dnl42 Posted April 6, 2019 Share Posted April 6, 2019 (edited) Today is the day when the GPS week number, which is transmitted as a 10-bit value, i.e., 0 to 1023, "rolls over." This means the current week number is 1023 and the next week (tonight at 23:59:42 UTC) is week 0, because as we all know, the lower 10 bits of 1023 + 1 is 0. Tomorrow will be the 3rd GPS week epoch. The previous roll-over was in August 1999. This will apparently be the last such event anyone reading is likely to experience, as the Modernized GPS system (MNAV and CNAV) uses a 13-bit week number, kicking this particular can down the road by 157 years and 28 weeks. I was told by a British colleague that the British tax year also starts on April 6. As our employer is geek central, he also mentioned the history of the tax year, which included a discussion of older notions of the first day of the year as well as the Julian and Gregorian calendars. Edited April 6, 2019 by dnl42 doh: today is Apr 6!!! Quote Link to post Share on other sites
