How the seasons have moved in your lifetime
How the seasons have moved in your lifetime: this guide has a section for each city: the start date of thermal spring, summer, autumn and winter by decade…
This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
This guide has a section for each city: the start date of thermal spring, summer, autumn and winter by decade since 1961, days above 25 C and below -20 C per decade, the growing season lengthening at both ends, ice days lost, and the first-snow date drifting later. Every number computed from the same open series with the method written out, so a teacher, a gardener or a journalist can check it. A focused example is "Tartu: the season calendar in 1961 and now".
How to use it
Use How the seasons have moved in your lifetime to compare stable place facts and official facilities. Live opening, access and disruption information should always be confirmed with the operator before travel.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
