समय: in Sanskrit grammar refers to the concept of time, which is crucial for constructing sentences in past, present, and future tenses. It helps in understanding the timing of actions described in sentences. For example, 'अधुना' indicates the present time, while 'श्व:' refers to tomorrow, showing future tense.

In Sanskrit, '10:15' is expressed as 'सपाददशवादनम्'. Here, 'सपाद' means a quarter past, and 'दशवादनम्' means ten o'clock. This method combines the base hour with the fraction of the hour passed, similar to how time is often expressed in Sanskrit.

'प्रात:' refers to the morning time, typically from sunrise until noon, while 'सायं' refers to the evening time, from late afternoon until night. For example, 'प्रात: पञ्चवादने' means at 5 in the morning, and 'सायं सप्तवादने' means at 7 in the evening.

In Sanskrit, 'I go to school at 7:30 AM' is expressed as 'अहं प्रात: सार्धसप्तवादने विद्यालयं गच्छामि'. Here, 'सार्धसप्तवादने' means half past seven, combining 'सार्ध' (half past) with 'सप्तवादने' (seven o'clock).

'वादनम्' is used in Sanskrit to denote 'o'clock' in time expressions. It is appended to the number indicating the hour. For example, 'दशवादनम्' means ten o'clock. This term is essential for constructing precise time expressions in Sanskrit.

'Quarter to' in Sanskrit is expressed using 'पादोन' before the next hour. For example, 'पादोनदशवादनम्' means quarter to ten, or 9:45. 'पादोन' indicates that a quarter hour is left until the next full hour.

'अर्ध' signifies 'half past' in Sanskrit time expressions. It is used before the hour to indicate that thirty minutes have passed. For example, 'अर्धनववादनम्' means half past nine, or 9:30. This term is crucial for expressing half-hour intervals.

'Midnight' is expressed as 'मध्यरात्रि:' and 'noon' as 'मध्याह्न:' in Sanskrit. These terms are used to denote 12:00 AM and 12:00 PM, respectively. They are important for distinguishing between the two halves of the day in time expressions.

The Sanskrit term for 'minute' in time expressions is 'निमेष:' or 'क्षण:'. However, traditional Sanskrit time expressions often focus on hours and their fractions rather than minutes, using terms like 'सार्ध' for half past and 'पादोन' for quarter to.

'त्रिवादनम्' signifies three o'clock in Sanskrit. It is a straightforward time expression where 'त्रि' means three and 'वादनम्' means o'clock. This form is used for exact hour expressions without minutes.

In Sanskrit, 'half past' is expressed with 'अर्ध' before the next hour, indicating 30 minutes past, like 'अर्धसप्तवादनम्' for 6:30. 'Quarter past' uses 'सपाद' before the current hour, like 'सपादषड्वादनम्' for 6:15, showing 15 minutes past.

The Sanskrit expression for '12:00 PM' is 'मध्याह्नवादनम्'. 'मध्याह्न:' refers to noon, and 'वादनम्' means o'clock, combining to denote midday precisely. This term is used in daily schedules and rituals.

In Sanskrit, 'The meeting starts at 11:00 AM' is expressed as 'सभा प्रात: एकादशवादने प्रारभ्यते'. 'प्रात:' indicates AM, and 'एकादशवादने' means eleven o'clock, specifying the exact start time of the meeting.
