词汇 | gregorian calendar |
词源 | Gregorian calendar. While an improvement on its predeces- sors, the inaccurate julian calendar resulted in the calendar year gradually losing on the actual solar year, or the time it takes the earth to travel around the sun. By the 16th century, for example, the first day of spring came on March 11, instead of March 21. As this interfered with seasonal church celebra- tions, Pope Gregory XIII introduced a modified calendar in 1582. He decreed that the day after October 4 in that year would be October 15, making up for the lost days in this way and ensuring that they would not be lost again by ruling that century years would no longer be leap years unless divisable by 400. Pope Gregory himself probably did not devise the “new style” calendar, but it was named in his honor. Immediately ac- cepted in Catholic countries, the Gregorian calendar wasn’t adopted in England or America until 1752—when the calendar gained 12 days overnight. Imperfect itself, it is nevertheless used today throughout most of the world. |
