I'm unable to replicate this on master. Can you please provide a failing test?

devilbes commented 6 years ago

@espen Yes, sure... On your website in demo: https://jakubroztocil.github.io/rrule/#/rfc/FREQ=WEEKLY;COUNT=30;WKST=MO;BYDAY=FR: Select the checkbox "byweekday" => "RRule.FR"... And you see March 22 will issue Thursday

this problem, only with the fourth or fifth Friday in March .....

Unable to replicate it. Might be DST issue though.

devilbes commented 6 years ago

@espen I understood the problem, this happens on the day when the clock is switched from daylight saving time from IST to IDT

espen commented 6 years ago

Yeah, there are some other issues dealing with DST so keeping this one closed.
