Compact GPS and Day-of-Year Calendars


In working on the archiving of GPS data for SCEC, I found it useful to have calendars available that would show, for any date, the day of the year (sometimes incorrectly called the Julian date) and also the GPS week number. For what they are worth, these are available here, in four different versions. Image cal.gps.2008.png

The general layout is shown in the figure: months run vertically, and days of the month horizontally. (This example is cut off in October to fit more conveniently in a browser window). I have used spaces rather than lines to make it easy to read across. For each day, the day-of-year number and day of the week are shown, except for Sunday, the first day of the GPS week, when the week number is given. For each week, Sunday is day 0, and Saturday day 6. The different forms available are:

Another collection of GPS calendars is available from the National Geodetic Survey, though I do not think these are as readable.
