The TIMEVALUE function in Excel is used to convert a time represented as a text string into a decimal number that Excel recognizes as a valid time. This is essential when you’re working with imported data, manual text entries, or systems that output time as text, and you need that information to behave like real time values in calculations or formatting.

The TIME function in Excel is used to combine hours, minutes, and seconds into a single valid Excel time. This is especially helpful when you're working with separate components of time and need to assemble them into a time value that Excel can understand and format correctly.

The SECOND function in Excel allows you to extract the second component (0 to 59) from a time or a date-time value. This is especially useful for time tracking, timestamp breakdown, and any situation where seconds matter—such as logging system events or analyzing performance durations.

The NOW function in Excel returns the current date and time based on your system clock. It is a volatile function, meaning it updates automatically every time the worksheet recalculates. This function is essential for timestamping, dynamic dashboards, real-time calculations, and time tracking systems.

The NETWORKDAYS.INTL function in Excel is a powerful upgrade of the NETWORKDAYS function. It calculates the number of working days between two dates with the flexibility to define which days of the week are considered weekends and exclude optional holidays.

The NETWORKDAYS function in Excel is a built-in date and time function that calculates the number of working days (excluding weekends and optionally holidays) between two dates. It’s widely used in project management, HR leave tracking, finance, and operations to determine how many business days are available or used.

The MONTH function in Microsoft Excel returns the month from a given date. It's widely used in financial reports, project planning, seasonal analysis, and any scenario where understanding or grouping data by calendar months is required.

Time values are essential in scheduling, data logging, and performance tracking. Microsoft Excel’s MINUTE function allows users to extract the minute portion from a given time value. Whether you’re analyzing call durations, meeting times, or timestamps in system logs, this function helps streamline and structure your time-based data.

In global business environments, especially across Europe and international organizations, week numbers often follow the ISO 8601 standard. Microsoft Excel offers the ISOWEEKNUM function to simplify working with ISO-standard week numbers.

Time-based data plays a crucial role in many industries—from employee shift tracking to call center analysis and performance dashboards. The HOUR function in Excel provides a simple way to extract the hour portion of a time value, making it easier to group, analyze, and visualize data by hour intervals.

The EDATE function in Excel allows you to add or subtract a specific number of months to/from a given date. This is especially helpful in financial forecasting, due date calculations, recurring billing schedules, and project planning.

The DAYS360 function in Excel calculates the number of days between two dates based on a 360-day year (12 months of 30 days). This function is primarily used in financial and accounting applications, such as calculating accrued interest, loan schedules, and bond pricing—where many conventions assume a 360-day year for simplicity.

The DAYS function in Excel allows you to calculate the number of days between two dates. This is useful for tasks like calculating age in days, determining time remaining until deadlines, measuring project durations, or analyzing the difference between start and end dates.

MS Excel: DAY function to extract day numbers from dates

The DATEVALUE function in Excel is designed to convert a date stored as text into a proper Excel date value. This is especially useful when importing data from external sources (like CSV files, databases, or manual entries) where dates are not always formatted correctly for calculations.

The DATE function in Excel is one of the most essential tools for anyone working with time-based data. It allows you to create a valid Excel date from three separate inputs: year, month, and day. Whether you're building financial models, automating reports, or managing timelines, the DATE function ensures accurate and consistent date creation.

The VALUETOTEXT function in Excel is designed to convert any value—number, text, logical, or array—into a text string. Introduced in Excel 365, it’s especially useful for debugging, auditing formulas, or displaying underlying data clearly in dynamic reports or dashboards.

The VALUE function in Excel converts text representations of numbers into actual numeric values. This function is especially helpful when numbers are stored as text and you need to perform mathematical operations on them—like sums, averages, or comparisons.

The UPPER function in Excel is used to convert any text string into uppercase letters. It is especially useful when you need to standardize text formats across your data—such as customer names, product codes, or locations—so that everything appears in a consistent, capitalized style.

The UNICODE function in Excel returns the numeric Unicode code point of the first character in a text string. It’s the counterpart of the UNICHAR function, which does the reverse (i.e., returns a character based on a Unicode number).
