Time Until Worksheets
Over the course of these worksheets, you will learn how to find the amount time between two separate times. This will as a result teach you how to determine time duration as well. Students really need to pay attention to the time of day (am or pm) that these times are set in. When they are in the same portion of the day, it is not a difficult skill at all. When the frame crosses over the two of those, it elevates the difficulty significantly. We walk you through how to process both of the problem types in the lessons and down below. These lessons and worksheets will teach students how to calculate the amount of time remaining until the start of an event.

- Two and a Half Hours Step-by-Step Lesson- What time will it be in two and a half hours. Draw it on the clock.
- Guided Lesson - More name the time and draw the time activities.
- Guided Lesson Explanation - You should always treat the minutes and hours like place values, that will make it work for you.
- Practice Worksheet - What time was it and what time will it be type of questions.
- Matching Worksheet - Match the advancing and rewinded clocks with the time changes.
- Answer Keys - These are for all the unlocked materials above.
We put your students in real world situations for the practice sheets that go home with them.
- Homework 1 - Write how much time is there until the time indicated? The picture of the clock indicates the current time. All times are with the same 12-hour period.
- Homework 2 - You look at the alarm clock after a long period of sleep. How long until you start your workday?
All of these printables are more colorful to help liven up your discussions in class.
- Practice 1 - Based on the time on the clock, how much time is until each event takes place.
- Practice 2 - Write the amount of time until the events take place. The current time is on the clocks.
Time Until Quizzes
These are really helpful for seeing where your students are at with this skill.
- Quiz 1 - This is the easier one of the two because we do not pass over the 12-hour threshold.
- Quiz 2 - The clock you are looking at is set in p.m. You will have events that take place over that meridiem threshold.
How to Calculate Time Duration Between Two Time
Learning how much time exists between two events or times is common task we will do almost on a daily basis for our entire adult lives. When we are able to determine this value, it indicates our entire schedule for the day. As we grow our priorities shift and what we focus our attention on changes quite often but understanding how to manage these events does not.
When we are looking at an analog clock to see what time it is, it is a fairly simple task since we have the idea of time. We know that if the big hand of the clock is pointing at 3 and the small hand is pointing at 8, the time is 8:15. That could be either in the am or pm which indicates the general period of the day. You will find that am loosely translated means “before midday”, and pm translates to after “midday”. This means that am is associated with the morning and pm with the evening. This will become important as we begin to learn more about time duration.
Time duration is a measure of the start and stop of an activity, but mathematically it is the same thing as finding the difference between two times. To calculate this value is not much different than another subtraction-based problem. If the two times are found in different 12-hour frames (am vs. pm) it can complicate things a bit. We will work you through both applications.
Calculating Duration in Same Frame - For example, if the time right now is 2:30 pm, and you need to know how many minutes it would take till its 5:30 pm, all you need to do is subtract. They are both in same time frame (pm), so you do not have to account for that. It would follow as:
As we can see there is a 3-hour difference between these times.
Calculating Duration Over Different Frame - For example, if the time right now is 11:20 pm, and you need to know how many minutes it would take till its 2:45 am. This is slightly more complex because you just cannot follow straight subtraction. There are many ways to find the solution here, but one strategy that most students seem to have success with is finding the difference of each time from the standard (noon or midnight) and then adding those times together. In this case our standard would be midnight (12:00 am) because that is where this duration 11:20 pm -> 2:45 am crosses over. We will see how far each of those values differs from the midnight standard:
11:20 pm -> 12:00 am = 40 minutes
12:00 am -> 2:45 am = 2 hours 45 minutes
We then simply add those values to find the total duration. 40 minutes + 2 hours 45 minutes = 3 hours 25 minutes.
Why Is This Skill Important?
There are very few things in this world that cannot be purchased. Time is something that you will never get back, nor can you purchase more of it. Understanding how much time you have available is a critical aspect towards being hyper productive. There are some things that you can do that takes hours to complete and others can be done in just minutes. If you are aware of how much time you have available to complete these tasks and how long they take to complete, you can complete more of them successfully.
