WebTag-tommarrow day length
Currently, in my location we are gaining about 1 minute and 20-30 seconds a day in daylight each day. Yesterday this Cumulus web tag:<#tomorrowdaylength>, displayed 1minute 28seconds as the gain for today. Today it is displaying just 20seconds of extra daylight. Any idea what happened to the extra minute we usually get? I have not moved from my current location.....

Re: WebTag-tommarrow day length
I don't know, sorry. Possibly due to the 'feature' that someone discovered recently where the sun times that Cumulus provides (via a third party library) update at midnight UTC (rather than local time). It may be getting sunrise from one day and sunset from an adjacent day, so the total is off by a minute.
I advised a long time ago that that web tag is unreliable; I wanted to remove it but was asked to leave it in.

Re: WebTag-tommarrow day length
Steve, I am fine with that. This is the 1st time I've "noticed" a discrepancy.Its not something I look at every day, but did notice it yesterday and today. I actually looked at it after my wife said something to the effect..."Are the days getting any longer now?"....A question I get asked about this time every winter!

Re: WebTag-tommarrow day length
I've never seen any problems with this webtag and I do tend to watch tomorrow's day length regularly.
