Calendar date truncator

World's simplest time tool

With this browser-based application, you can truncate a calendar date and drop the months and/or days components from it. You can also drop the time part from a date via an additional set of options. When truncating the time part of a date, you can further narrow down the truncation to minutes and seconds. Also, you can control the padding of date components in the output and turn the dropped months and days into "01", and the dropped hours and minutes into "00".

Calendar date truncator tool What is a calendar date truncator?
This is a quick online utility for truncating calendar dates. It allows you to shorten the given date by removing the smaller date components and making the date less accurate. In particular, you can drop days from a date (and leave years and months) or drop both months and days (and leave just the years). By using the tool options, you can independently control the truncation of the date and time components. For example, if you have a date "2022-05-13", then by dropping the day, you will get "2022-05", and by dropping the month and the day, you will get "2022". You can also remove the time part from the date. For example, you can convert "2022-05-16 17:45:30" into "2022-05-16". Similarly, you can remove minutes and seconds and get a date with the hours "2022-05-16 17". You can also mix the truncation of the date and time components. For example, you can remove days and seconds and get "2022-05 17:45". If you only want the dropped components to be zeroed out (and not completely removed), you can activate the option to display "01" for the dropped date components and "00" for the dropped time components. For example, if we drop months, days, and seconds from "2022-05-16 17:45:30" and we zero out these components, we'll get "2022-01-01 17:45:00" as the result. In addition, you can control the padding of date and time components. If you have a date such as "2022-5-4" then when padded, the months and days will be made two digits wide, making it "2022-05-04". Timeabulous!

Drop the Time Part from Dates
In this example, we get rid of the time part of multiple calendar dates. We remove the hours, minutes, and seconds by selecting the "Truncate All Time" option. Each of the entered dates is converted from the format "YYYY-MM-DD hh:mm:ss" to format "YYYY-MM-DD".

Remove Months and Days
In this example, we remove months and days from five calendar dates and turn the minutes and seconds in the clock part into zeros by enabling the "Print "00" For Time" option. We also turn off the time/date component padding option, and as a result, we get dates that have the format "YYYY h:0:0".
