Calendars and Scheduling
Add tides to Google calendar.

1) Go to http://tides.mobilegeographics.com/ and download the .ics file for this year for your location – this example is for Naha, Okinawa: http://tides.mobilegeographics.com/locations/4013.html
2) Import the resulting 4013.ics file into Google Calendar:
IMPORTANT: it’s best to import it to a new calendar named “tides” so you can always switch the display off when you want to – if you import it into your main calendar you’ll be stuck with it for the year!
3) Doing the above makes quite a lot of entries since it also displays low tide, sunrise and sunset – you can use http://www.gcaltoolkit.com/online-guide to delete entries with the text “sunrise” “low tide” etc so you are left with just the high tide information.
