看不懂 */15 9-18 * * 1-5 这种表达式?粘贴进来,这里把它翻译成人话,逐个字段解释含义,并按下方的当前时间算出接下来 5 次到底什么时候运行。Can't read an expression like */15 9-18 * * 1-5? Paste it here for a plain-language translation, a field-by-field breakdown, and the next 5 actual run times in your local timezone.
注意:本工具按经典 Vixie cron 的语义计算——当「日」和「星期」两个字段都有限制时,cron 的规则是两者取「或」(任一命中就执行),与很多人的直觉不同,配置时要留意。星期里 0 和 7 都表示周日。Note: this tool follows classic Vixie cron semantics — when both day-of-month and day-of-week are restricted, cron runs when EITHER matches (OR, not AND). For day-of-week, both 0 and 7 mean Sunday.
