rrule 第 N 天之后的星期几

Question

每年六月第三个星期一之后的星期二写规则的最佳方式是什么？

目前我这样写规则：

rule_mo = rrule(freq=YEARLY,              
            bymonth=6, 
            byweekday=MO(+3),
            ...)
rule = (x + relativedelta(weekday=TU(+1)) for x in rule_mo)

有没有办法只使用rrule 而不必使用relativedelta 来编写整个规则？

Answer 1

参考：http://jkbr.github.io/rrule/

rule = RRule.fromText("every June on 3rd Tuesday")

rule.origOptions    
{
   freq: RRule.YEARLY,
   bymonth: [6],
   byweekday: [RRule.TU.nth(3)]
}

rule.toString()     

FREQ=YEARLY;BYMONTH=6;BYDAY=+3TU

rule.toText()   every June on the 3rd Tuesday
