AB does not like the mathematical sign for "less than". So:
Although today is the Winter Solstice (that is, the shortest time between sunrise and sunset for those pedants pointing out (quite correctly) that all days are approximately 24 hours long) those wishing for “lighter mornings” will have to wait a little longer.
In London the length of the day today is 7hrs 49m 44secs. This is also the length of the day tomorrow (to the nearest second) though tomorrow is longer by less than 1 second. However, whilst sunrise today is at 8:03am (to the nearest minute), the time the sun rises continues to get later until January 1st when it rises at 8:06am, You have to wait until January 11th before to see the sun rise earlier than it does today, when it rises at 8:02am. However, by then the length of the day has increased considerably to almost 8hrs 12mins with this increase being attributable to later sunsets, which get later by well over a minute a day.
A similar, though not quite pronounced, phenomenon occurs around the Summer Solstice in June but this time with the sunset. The latest sunset is not on 21st June but on 29th. The decrease in length of the day which occurs between 21st and 29th is down to later sunrises.
