Для правильного использования предлогов времени 'at', 'in', 'on' нужно учитывать, к какому типу времени относится объект:

• 'at' используется для указания точного времени (at 7 o'clock), для обозначения времени суток (at night, at noon, at midnight) и для праздников (at Christmas).
• 'in' используется для обозначения частей суток (in the morning, in the afternoon, in the evening), месяцев (in January, in December), сезонов (in summer, in winter), годов (in 2023) и более длительных периодов времени.
• 'on' используется для обозначения дней недели (on Monday, on Friday) и конкретных дат (on December 31st).
