Before I create this, I want to flag a conflict in the request:

- **09:00 UTC** (your stated standup time) is **02:00 US Pacific** during PDT (until Nov 2, 2026) and **01:00 US Pacific** during PST.
- **09:00 US Pacific** would be **16:00 UTC** (PDT) or **17:00 UTC** (PST) — seven or eight hours after your standup.

So a hold set to "09:00 US Pacific" would not line up with a 09:00 UTC standup.

A couple of other things:
1. I don't currently have access to a calendar tool in this environment, so I can't actually create the event — I can only help you get the details right.
2. Which did you actually mean?
   - **Match the standup:** recurring hold at **09:00 UTC** = 02:00 Pacific (note: this shifts by an hour relative to local time at DST changeovers unless anchored to UTC).
   - **Literally 09:00 Pacific:** I can draft that, but it won't coincide with the standup.

Also worth deciding: recurrence pattern (daily, or weekdays Mon–Fri?) and duration (e.g., 15 or 30 minutes).

Let me know and I'll put together the exact event details (or an .ics file) for you.
