That information is clearly conflicting with timeanddate. According to the diagram on your link it says that the equator receives constant 14 hour days throughout the year. According to dateandtime the city of pontianak, which is on the equator, is going to see a little over 12 hours of daylight today. In fact, according to dateandtime, however true or false those predictions might be, that location on the equator will never experience a 14 hour day.
You apparently did not do any research at all into this subject. Why should we assume that your source is accurate and agrees with all other sources?
You're misreading the chart. The equator is in the bright green band representing the 12-to-14-hour-day. For most of the year, the equator has just slightly more than 12 hour day. The black line separating the yellow region from the green region, that's the "14 hour day" line, which never comes close to the equator (and is never at any particular latitude for long either, meaning nobody has a "constant 14 hour day")
I don't understand Mr. Bishop's confusion.
The chart looks very straightforward in showing the equator as always being close to the green or 12 to 14 hour day band on the chart.
In Dallas, TX, USA , today, Sunrise was at 6:55 AM ; Sunset at 8:04 PM ; a 13 hour, 9 minute day.
Looks close to between the 12 and 14 hour bands.
Tomorrow's Sunrise will be 6:56 AM (Sunset not listed) indicating the day is getting shorter, approaching the Autumnal Equinox, or 12 hour day / 12 hour night at some date in September. (Would have to look it up - Friday, September 22, 2017 , 3:01 PM in Dallas)
The equinox seems to be on September 26 for Dallas.:
Sunrise 7:18 AM; Sunset 7:18 PM. But the "Daylength" is listed as 11:59:10.
Interesting chart.
I am admittedly not as smart nor as intellectual as Mr. Bishop, but I had no problem in reading the chart.
It would have helped to have it all for all the hours, not just the even ones.
