关于此工具
季节是地球以23.5°轴倾斜绕太阳公转而产生的自然气候周期。在温带地区尤其重要，对于规划户外活动、预测天气、追踪季节性趋势和研究气候模式等许多情况都很有用。然而，要准确判断某个日期属于哪个季节，需要理解气象学季节的定义。
此工具可以计算您输入的任何日期在北半球或南半球的气象季节。只需选择日期和半球，然后点击"Find Season"即可查看该季节的名称、开始和结束日期、自季节开始以来已过去的天数，以及剩余的天数。结果包含一个带有代表每个季节的表情符号的可视化摘要卡片。
气象季节是根据日历月份定义的（北半球：春季3月至5月、夏季6月至8月、秋季9月至11月、冬季12月至2月）。这比基于至分点和分点的天文季节更简洁、更一致。此工具特别适合气象预报员、教育工作者、学生、计划跨半球旅行的旅行者，以及任何对季节时间感兴趣的人。
