With this browser-based application, you can calculate the difference between two or more calendar dates. You can find the number of years/months/days that have passed since a certain date, compare peoples' ages, and find time interval changes to the nearest second.

This is a quick online utility for finding how much time has passed between several calendar dates. For example, if you want to find the age difference between a father and a son, or if you want to know how many days in your life you have lived, or if you want to know how much time is left till the end of the year (or century), then this program easily can do such calculations. To compare two calendar dates, enter one date per line in the format YYYY-MM-DD or YYYY/MM/DD. For example, enter a father's birthday "1980-03-24" and a son's birthday "2012-11-02", and you'll get the age difference of "32 years, 7 months, 9 days". For more accurate calculations, you can add time in HH:MM:SS format at the end of the date. For example, you'll find that difference between "1980-03-24 20:45:50" and "2012-11-02 05:50:51" is "32 years, 7 months, 8 days, 9 hours, 5 minutes, 1 second". You can also specify a 12-hour time, such as "6 am" or "09:20 pm". If you want to find the difference between several calendar dates, enter them in a column one after another. Additionally, you can find the difference between individual groups of dates. To use this feature, separate the groups with three dashes "---". All in all, the program supports 13 various date difference output formats. It can be in the full-text format (that includes years, months, days, hours, minutes, seconds), or it can be the digital calendar format "0032-07-08 09:05:01", or the output can be just the time interval in days "11910.38 days", weeks "1701.48 weeks", months "391.28 months", or the exact seconds. When calculating the differences of several dates, you can use the option to keep the structure of dates so that each date is displayed in the output field on the same line as in the input. If you are only interested in the time difference, you can use our time difference calculator. Timeabulous!

In this example, we calculate the difference between two calendar dates – one date in 2022 and the other in 2032. We use the full date format, including hours, minutes, and seconds. The program subtracts the first date from the second and finds the difference equal to 10 years, 10 months, 6 days, 5 hours, 30 minutes, and 25 seconds.
In this example, we use this program to count the number of days pairs of consecutive years to find the next leap year. We separately compare 2022 and 2023; 2023 and 2024; and 2024 and 2025 years by putting dashes between the pairs of years. We set the output format to days and find that 2024 is a leap year, consisting of 366 days.
In this example, we decided to compare the ages of all family members. In the first block, we compared the ages of the three children given in the format YYYY-MM-DD HH am/pm. In the second block, we compared the birth years of the father and mother. And in the third and fourth blocks, we compared the ages of grandparents.
