Ice Saints are days in May known for causing frost damage due to cold air incursions. The Ice Saints are an important guide when planting, especially for hobby gardeners.

The 100-year calendar predicts what the weather will be like in spring. According to the farmers' calendar, the Ice Saints could actually invade in 2024. The first half of May is expected to be mixed this year, but the calendar also makes a holiday for May 1st. Towards the end of the month, at the time of the Ice saints, it will get cooler and sometimes even frosty. Especially on May 24th it will be cold in the morning. For the period of May 4th to 15th, the calendar predicts warmer but still mixed weather with some rain and occasional thunderstorms. But the calendar is not scientifically proven, it can only serve as a rough weather orientation and can only be used as a suggestion from the calendar. The calendar says nothing about whether Ice Saints will bring frost and cold in 2024 and when the Iceaints will bring cold in 1924.
