[BUG]: Wrong month in upcoming node

[overlinden]

Describe the bug
I have a calendar (google ical) with all birthdays of my contacts. The birthday within the ical is correct but the date in the calendar object returned by the upcoming node is wrong.

To Reproduce
Steps to reproduce the behavior:

1. Create an annual event in the google calendar
2. Create a public ical link for that calendar
3. Add the calendar to the upcoming node
4. Connect the upcoming node to a debug node and check the message returned

Expected behavior
The dates (startdate and enddate) should math the ones in the calendar.

Screenshots
Node configuration:

I downloaded the ical file and checked the event section:

BEGIN:VEVENT
DTSTART;VALUE=DATE:20210130
DTEND;VALUE=DATE:20210131
RRULE:FREQ=YEARLY;WKST=MO;INTERVAL=1;BYMONTHDAY=30

END:VEVENT

But the msg looks like:
