It could do best it can, i.e. local national holidays. In G.B. I think they are called "bank holidays." However, good point. My Mac calendar already has holidays marked, and I just noticed that the Quicken calendar does not. I had assumed that Quicken would localize itself along with language and configuration of the computer but seems I was wrong. hmm...

I voted for it, although not sure it's necessary because... if you schedule a payment on the last day of the month, and that day is a bank holiday or weekend, the bank will normally automatically adjust the payment to be made on the last bank work day prior. At least that's how it works with my bank.
just a calendar that respects the local national holidays, like New Years Day, etc...
To the person who wanted a reminder to be scheduled every 3 years:
Since you can't do "Yearly every [x] years" ... How about Monthly every  months on the [day] ?
I'm on Q Win 2018 and it looks like we're still all waiting for the "Daily" types of durations.
I didn't state it explicitly in my original request, but a "Daily, every [xxx] days" needs to be included here.
There have been several requests for a "Daily, every  days" since this was originally posted. And, no, "Monthly" or "every 4 weeks" does not appear to cut it. It must be exactly "every 30 days".See an earlier post by Mark Baribeault in this message thread.
