Adding hours in Google Sheets is a fundamental skill for managing time-based data. Using built-in functions, you can efficiently sum hours across rows and columns.

We'll provide step-by-step guidance on how to add hours accurately in Google Sheets. You'll also learn tips to avoid common pitfalls.

Finally, we'll explore why Sourcetable is a better alternative to using Google Sheets. Sourcetable makes it easy to become an advanced spreadsheet user faster as an AI-first spreadsheet.

### Using the TIME Function

To add hours in Google Sheets, leverage the TIME function. This function converts hours, minutes, and seconds into a time format that Google Sheets can process. The syntax for adding hours is: =Start time + TIME(N hours, 0, 0). This method enables you to add hours, minutes, and seconds effectively within a single formula.

### Basic Math Approach

An alternative to the TIME function is to use basic math for adding hours. You can write: =Start time + (N hours / 24). This formula divides the number of hours by 24 to convert it into a fraction of a day, which Google Sheets can then add to the start time.

### Using Duration Syntax

Google Sheets also allows the addition of time using duration syntax in the format hh:mm:ss. For instance, to add 1 hour, 1 minute, and 1 second, use 01:01:01. Use the + operator with this syntax to add time values, such as =Start time + "01:01:01".

### Working with Multiple Rows

To add hours across multiple rows, use the SUMPRODUCT function. This function helps to sum time values efficiently when working with data spread across various rows or columns in your spreadsheet.

### Handling Midnight Crossings

When calculating durations that cross midnight, add dates to your time units. This ensures accurate computation. Use an IF function to handle scenarios where the start time is before midnight and the end time is after midnight, by setting conditions based on specific time values.

### Formatting Time Correctly

Utilize the TEXT function in your formulas to set up the correct time format. However, remember that Google Sheets does not tally text values. To ensure times are summed correctly, apply a custom time format instead of using the TEXT function for summation.

Using Google Sheets, the SUM function allows users to add multiple time entries formatted as hh:mm or hh:mm:ss. This feature is crucial for tracking total hours worked or summing various time durations, ensuring efficient time management.

### Calculate Overtime

With functions such as IF and SUM, users can easily calculate overtime hours by comparing total hours worked to standard working hours. Formatting the result in hh:mm or using custom formats can help display the data clearly.

### Time Tracking for Projects

Google Sheets facilitates project time tracking by allowing users to sum up hours spent on different tasks using the SUM or SUMPRODUCT functions. Custom formatting ensures clarity when presenting total hours spent on a project.

### Shift Scheduling

By adding hours in Google Sheets, managers can streamline shift scheduling. Functions like NOW() and TIME can be used to calculate shift durations and ensure that schedules do not overlap, optimizing workforce allocation.

### Payroll Calculation

The ability to sum hours allows businesses to calculate payroll accurately. Using SUM and custom formats, users can track total hours worked and compute wages based on hourly rates, simplifying payroll processes.

### Attendance Monitoring

Track employee attendance efficiently by adding check-in and check-out times. Google Sheets' HOUR, MINUTE, and SECOND functions help to extract hours and summarize attendance, ensuring compliance with working hours policies.

### Education and Study Time Logs

Students and educators can log study or instruction hours using Google Sheets. The SUM function simplifies adding different periods, providing a clear overview of time spent on educational activities.

### Personal Time Management

Individuals can use Google Sheets to track personal activities by adding up hours spent on various tasks. Functions like SUM and TEXT help format and visualize time management, promoting productivity.

## How to Add Hours in Sourcetable

Sourcetable simplifies time-consuming tasks, making even advanced spreadsheet operations accessible to everyone. To add hours in Sourcetable, you can utilize its AI assistant for quick and accurate results.

How do I add hours using the TIME function in Google Sheets?

Use the formula =Start time + TIME(N hours, 0, 0) to add a specific number of hours, ensuring that N hours is less than 24.

To add more than 24 hours, use the formula =Start time + (N hours / 24).

What is a method to add hours in Google Sheets using basic math?

Add hours using the formula =Start time + (N hours / 24).

Use the TIME function to add hours, minutes, or seconds, and the SUM function to add up a list of times.

Make sure the cells being summed are formatted as time to ensure correct calculations.

How can I use the SUM function to add hours in Google Sheets?

Use the SUM function in Google Sheets to add hours by ensuring the time values are in the proper format and summing the relevant cells.

Can I use the TEXT function to add hours in Google Sheets?

Instead of the TEXT function, use the TIME function to convert time units, as TEXT returns values as text and is not suitable for summing.

## Conclusion

Learning how to add hours in Google Sheets can streamline your workflows and improve efficiency. However, using Sourcetable can make this process even easier.

Sourcetable integrates with third-party tools, allowing you to access your data in real time. The intuitive interface is designed for team collaboration.
