Ah! But crontab.guru is such a beautiful UI/UX! I'd argue it offers the user everything it needs to perform what it needs to perform.
I will painfully admit I hassle with going from PT/PDT --> UTC more than I should, but after a while it was pretty easy to commit a simple number of hours (+7/8, depending on daylight savings timing) to memory.
I used to use [Hour](https://apps.apple.com/us/app/hour-world-clock/id569089415?m...) for MacOS to avoid this problem; I'm sure there's a similar or native solution for Windows & Linux as well.
