Good Morning!
I trusted what Fleur wrote. I don't check everything that others document. Especially since Fleur is a very experienced observer.
Personally, it doesn't matter whether it's today or tomorrow.
It's my first observation when they lay eggs. So I'm still learning.
What I have already learned is that Wikipedia is not a good source for such information.

Laying generally begins in late winter, sometimes later. One clutch per year of 1-4 white eggs are laid, measuring 56-73mm x 44.2-53mm and weighing 75-80g. They are normally laid at 3 days intervals and are incubated by the female alone, starting from the first egg, for 31-36 days. During this time, she is fed at the nest by her mate.
Once hatched, the young are brooded for about 2 weeks; the female stays with them at the nest for 4-5 weeks. For the first 2-3 weeks the male brings food to the nest or deposits it nearby, and the female feeds small pieces the young. At 3 weeks the chicks start to feed themselves and begin to swallow smaller items whole. At 5 weeks the young walk around the nesting area, and at 52 days are able to fly a few metres. They may leave ground nests as early as 22-25 days old, while elevated nests are left at an age of 5-7 weeks.
Fledged young are cared for by both parents for about 20-24 weeks. They become independent between September and November in Europe, and leave the parents' territory (or are driven out by them). At this time the male begins to sing again and inspect potential future nesting sites.
Young reach maturity in the following year, but normally breed when 2-3 years old.......
