With this browser-based application, you can decrement a calendar date by a specific number of days, months, and years (and optionally also hours, minutes, and seconds). The decrement interval can be specified in the options and it works correctly with leap years and daylight savings adjustments. You can control the format of the output dates, the padding of date components (turn "3/2" into "03/02"), and also print the day of the week. Created by computer nerds from team Browserling.

This is a quick online utility for subtracting a custom date interval and a custom time interval from one or more calendar dates. It primarily focuses on subtracting dates (years, months, days) but for fine-tuning the results, you can also subtract clock times (hours, minutes, seconds). For example, if goods delivery happened a day earlier than expected, you may need to adjust a report by one day and move dates to yesterday. Or maybe you're wondering what day of the week was exactly 100 years ago. With this tool, you can easily turn time back and shift any date by any time interval backward (if you need to work with future dates and add an interval to a date, then you can use our increment dates program). The dates you'll be working with must be entered in the input one per line in a vertical column. The input dates are accepted in the format "YYYY-MM-DD" or "YYYY/MM/DD". They can also be extended with clock hours "YYYY-MM-DD hh:mm:ss". Additionally, they can be abbreviated to just months "YYYY/MM" or only years "YYYY". The decrement interval can be specified in the options using English words "year", "month", "day", "hour", "minute", and "second". For example, "2 years", "3 days 10 minutes", "100 months", or "3y 6mo 10d 20h 30m 50s". The results of subtracted dates are displayed in the output field. You can choose from a variety of output date formats that include the US and European date formats, computer date formats (such as ISO 8601), and full text English formats that spell out the name of the month and the day of the week. If you select the custom date format mode, then you can create original output date printouts using format-string abbreviations. To display years use "YYYY", months – "MM", days – "DD", days of the week – "dddd", hours – "hh", minutes – "mm", and seconds – "ss". You can also add padding to each calendar date and switch from 24-hour to 12-hour clock time format. Timeabulous!

In this example, we decrement a calendar date by 1 month, 20 days, and 900 minutes. We choose the output date format to be "MM/DD/YYYY hh:mm:ss" and activate the padding option that converts single-digit months and days to double-digit months and days.
In this example, we jump back 40 years and turn the nineties into the fifties. We set the decrement interval to "40 years" and get all 1990's dates converted to 1950's dates. We display the decremented dates in a format that includes the full name of Gregorian calendar months (January, February, etc) and days of the week (Monday, Tuesday, etc).
In this example, we enter dates of the first day of spring for different years that are separated ten years apart. We subtract 14 hours and 30 seconds from each date. As the time components of the dates differ only by the part of the day (am/pm indicator) and as some of the years have a different number of days in February (28 or 29 days), we sometimes get February 28, sometimes February 29, and sometimes March 1 in each result.
In this example, we create a custom format for the subtracted calendar date. We format the output result as "year: YYYY, month: MM, day: DD" and subtract 20 months and 40 days from "3000-01-01".
In this example, we got curious about what weekday was exactly 100 years ago? To find out, we enter today's date in the input and subtracted a 100-year interval from it. It turns out, that 100 years ago it was Tuesday!.
In this example, we decrease the calendar date "2000-01-01 00:00:00" by 1 century, 1 month, 1 day, 1 hour, 1 minute, and 1 second. We use the ISO date format to set the decrement interval "0100-01-01 01:01:01" and get the output date "1899-11-29 22:58:59".
