We don't keep a diary as such, but do jot down a few things like when seeds are put in, when they come up. When we prune the Clematis, frosts etc.
How early or late the garden is, can be judged by the "lollipop" tree in the back garden, I won't go into what the lollipop tree is at the moment.
The leaves are just beginning to show now, and they are two weeks later than last year, but the same as the previous year.
Just wondered if you had any indicators in your gardens.
