Generate a List of Calendar Dates
I often have to generate a sequence of calendar dates so I created this simple online utility that does it for me. It lets you generate however many calendar dates you need starting from any date with any time interval between the dates. It works in the browser and is powered by alien technology from the future. This linear calendar date series generator works entirely in your browser and is written in JavaScript.
The sequence of calendar dates starts from the startDate and increases by the interval amount specified in the options. It operates with universal UTC dates and times and uses JavaScript language's built Date and Date. UTC objects. The startDate option may contain either date and time parts in YYYY-MM-DD hh:mm:ss format or just the date part in YYYY-MM-DD format.
The program uses a smart parsing algorithm to extract all the date and time components from the startDate value. For the date part, it finds the year, month, and day components, and for the time part, it finds hours, minutes, and seconds components. To start generating a list of dates, it creates the variable firstDate by composing Date and Date.
UTC objects: new Date Date. UTC y, mo, d, h, mi, swhere y is year, mo is month, d is day, h is hour, mi is minute, s is second. This makes sure that the firstDate object uses the UTC timezone. Then, in a similar way, it parses the interval option and sets up the dateInterval object.
This object contains the parsed interval in years, months, days, hours, minutes, and seconds. If you are generating a descending list of calendar dates, all components of the dateInterval object are turned into negative numbers via multiplying them by The date generator runs a for loop count times number of dates in the output, specified in options and each next date is obtained by calling the getNextDate function.
getTime and then updates individual date and time components in it online date format generator the next value by calling nextDate. setUTCX prevDate. After replacing all the nextDate components, the function saves the result in another variable called newDate and replaces the prevDate object with the nextDate object. Next, the date in newDate is formatted according to the desired output format. The formatting is done by repeatedly calling the format. replace X, newDate.
getUTCX function with X being yearmonthdayhourminuteand second. The formatted string is then pushed onto allStrDates stack and when the for loop finishes, the stack elements are joined into a long string via the allStrDates.
join separator function. Finally, the string is sent to the output area and is printed on your screen. This calendar date generator was created by me and my team at Browserling.
