An easier to interpret description: https://www.timeanddate.com/eclipse/lunar/2022-may-16 https://www.timeanddate.com/eclipse/lunar/2022-may-16 which given you

An easier to interpret description: https://www.timeanddate.com/eclipse/lunar/2022-may-16 https://www.timeanddate.com/eclipse/lunar/2022-may-16 which given your location tells you what to expect. For me the news is bleak: full eclipse begins at 05:23 local time, and sunrise is just 4 minutes later, so the darkening of the moon's face probably won't register against the rapidly brightening sky. But the site overall is a go-to for easily digested information on all things daylight.

Ironically, the website is called "timeanddate" and I'm still confused by the times on this site. Perhaps I'm reading it wrong... let me know. Right now it's 12:53 PST, and the countdown says it's about 5hr 38 mins to go until the eclipse begins, but then if you click the Seattle link on that page [1] it says it actually begins at 8:34 pm PST. On top of that, it shows the maximum at 9:11 pm PST. In short, maybe the countdown is 3 hours off? And it's trying to communicate the time left until the maximum?

  From further down on your link: - "6:32 pm: Penumbral Eclipse begins / Below horizon" - "8:29 pm: Total Eclipse begins / Below horizon" - "8:34 pm: Moonrise / Rising, but the combination of a very low moon and the total eclipse phase will make the moon so dim that it will be extremely difficult to view until moon gets higher in the sky or the total phase ends."

  Right now it's 12:53 PST I think you mean PDT. Which may or may not account for some of the miscalculation.

    People should give up on specifying the S or D in casual timezone references. Simply writing "12:53 Pacific" usually gets the point across. Incorrect usage of S during D times of year is far more common than the rare case where the indicator matters.

      Hard to say. Those in Arizona not in the Navajo nation wouldn't agree with you since they're still on MST. I usually say "PT/MT/CT/ET" for those not in the list of stateside exceptions since it just removes ambiguity.

        I just say "2 pm AZ" or "2pm utc-7", depending on who I'm talking to. MST is as likely to confuse someone ("oh, mountain time", then they're an hour off half the year) than it is to get it right.

        Whenever I've been on the Nation, I've always heard it referred to locally as simply "Denver time." See also : "Early, On time, and Navajo Time."

        Interesting, I've never met or encountered someone from the Navajo Nation so that's good to know! I always wondered how it was resolved there.

      That is something we should strive to correct people on. I've missed online events with friends because they would tell me "X pm PST", so I obviously just put the time in any time conversion app and end up being an hour late. It's easy for Americans, because you do your conversation by hand, for you people it means e.g. "one hour behind my time", but for everyone else who has to use an app to convert times, it's quite annoying and error prone. Though it might soon be moot given USA is moving to permanent DST, so rather than people using PST wrong some of the time, it will be all of the time.

How amazing is timeanddate.com? I freaking love this site so much. Somehow it always seems surprising to me, maybe because of the colors or slightly cartoony look or something, I can’t quite put my finger on it. But the content is so consistently top notch, clearly made by people who care.

  It's one of my favorite sites. I love the focus on high quality, easy to interpret information without click bait, intrusive ads, etc. I wish there were more sites like it.

  I actually very briefly looked into how get this basic data about sunrise/sunset/moonrise/moonset times and headings for any location on Earth (because I wanted to make a simple website to visualize the data as a fun side project). There must be some free/open source software models of the Sun-Earth-Moon system that could be combined with some basic GIS model of Earth to provide reasonably accurate data for any location on Earth, but I'm just so far away from these fields I probably don't know the right things to search for.

    Last time I looked into this I implemented some stuff from Astronomical Algorithms https://www.amazon.com/dp/0943396352 https://www.amazon.com/dp/0943396352 which was more fun for me than just grabbing the data.

    It basically depends on how accurate you want to be. I looked into this so I could generate lunar calendars for friends. I got the phases of the moon predictions from the BSD Games program pom by Keith E. Brandt[0], which is itself based on 'Practical Astronomy with Your Calculator'[1] by Peter Duffett-Smith. Lunar eclipse predictions came from the Basic Lunar Eclipse and Phase Calculator by Xavier Jubier[2]. These work well for the near future and with a reasonable amount of precision for regular people. You can get much more accurate using Astronomy Engine[3], but that was already a lot more complex than I wanted to get into [0] https://manpages.debian.org/bullseye/bsdgames/pom.6.en.html https://manpages.debian.org/bullseye/bsdgames/pom.6.en.html [1] https://www.cambridge.org/core/books/practical-astronomy-with-your-calculator/99F3416EDE80EAAED068A59EE3602AF2 https://www.cambridge.org/core/books/practical-astronomy-wit...

>darkening of the moon's face probably won't register against the rapidly brightening sky Full moons are always directly opposite the sun. You'd be more concerned about it disappearing beyond the horizon.

  Out of sheer cussedness I just took a look (45 mins before start of total eclipse). The earth's shadow is quite apparent at this point but the sky behind it is already quite pale. So I great that once the "bite" is complete the contrast to a normal full moon will be obscured.

Ha ha, I have better news: I cannot see it at all. So no alarm setting or FOMO needed!
