Here, time values are represented in terms of days, hours, minutes and seconds. The first calculator basically lets users determine the sum or the difference between two time-values. Each month either has 30 or 31 days, except the month of February which has 28 days in a normal year and 29 days in a leap year.

The total number of days in a calendar year are categorized into 12 months of varying lengths. In this calendar, a year is divided into 365 days, with the exception of a leap year, which has 366 days. These calculators use the Georgian calendar to make calculations. Jan, Mar, May, Jul, Aug, Oct, Dec have 31 days &įeb has 28 days in a normal year and 29 days in a leap yearĢ4 hours or 1,440 minutes or 86,400 seconds Here is a list of some basic units of time: So, while making calculations using the above calculators, it’s important to know some basic units of time and the calendar system used for designing these calculators. Time, as we know it, can range from several years to a few seconds. What is a time or a time duration calculator?Ī time calculator is an algorithmic digital tool that can be used to add/subtract various time-values and make different types of time calculations such as finding the time difference between two important events, determining the date 3 years before today, knowing how many hours, minutes or seconds are there in a year, etc.īasic things to know while making time calculations The output shown is either in terms of days, hours, minutes and seconds or only in terms of days or hours or minutes and seconds. The input provided in the ‘Start Time’ field should be earlier than that in the ‘End Time’ field. Additionally, users can also enter a certain time value by entering required details in the ‘hour’, ‘minute’ and ‘second’ sections and choosing between ‘AM’ or ‘PM’ in the ‘Start Time’ and ‘End Time’ fields or by clicking on the ‘now’ button to select the current time.Įnter the relevant details in the input fields and click on the ‘CALCULATE’ button to determine the time gap between two dates. Both the fields allow users to enter the start date or end date by either choosing the required date from a calendar or by entering the month, date and year in their respective sections. The calculator has a ‘Start Time’ and an ‘End Time’ field. The calculator finds the time difference between a certain time on a start date and a certain time on the end date. The value provided in the ‘hours’ section should be less than 24, that in the ‘minutes’ section has to be less than 60 and the input in the ‘seconds’ section should also be less than 60. The input provided in the hours, minutes and seconds sections of the ‘Start Time’ and ‘End Time’ fields need to be valid values. If the time-value provided in the ‘Start Time’ field is ahead of that provided in the ‘End Time’ field, then the calculator automatically assumes the ‘Start Date’ to be on the previous day. The output displayed is either in terms of hours, minutes and seconds or only in hours or minutes or seconds. Enter the required details in both the fields and click on the ‘CALCULATE’ button to know the difference between both the time values. Both the fields have options to enter the required number of hours, minutes and seconds and to choose between ‘AM’ and ‘PM’.

The calculator has two fields - ‘Start Time’ and ‘End Time’. The calculator can be used to determine the difference between two time-values. Value fields included in an expression are ‘Day’, ‘Hour’, ‘Minute’ and ‘Second’ denoted by the letters ‘d’, ‘h’, ‘m’ and ‘s’ respectively.įind the difference between two time-values Here, users can add and subtract a string of time-values using a mathematical expression. Make time calculations using mathematical expressions The time-value to be subtracted from the ‘Start Time’ consists of the value fields ‘Day’, ‘Hour’, ‘Minute’ and ‘Second’. The ‘Start Time’ comprises a date - which can either be filled directly into the relevant value fields or entered using the calendar - and a time value which has the value fields ‘Hour’, ‘Minute’, ‘Second’ and a drop-down menu to toggle between AM and PM. This time calculator allows users to either add or subtract a time value from a ‘Start Time’, where the ‘Start Time’ is represented by a particular date along with a certain time on that date. In case, a value field is left blank, the result would be displayed accordingly. The value fields ‘Day’, ‘Hour’, ‘Minute’ and ‘Second’ have been provided for both the time-values. Using the time calculator, users can either add two time-values or find the difference between two time-values.
