The DATEDIF function returns the difference between the start_date and end_date in years, months, or days. You could also apply Conditional Formatting to highlight when dates are overdue.Īnother option for calculating the remaining number of days is the DATEDIF Function. If you want to ignore negative numbers and show 0 instead, you can use the MAX Function: =MAX(0,B3-TODAY()) We can subtract today’s date from the deadline date by using the TODAY Function to get the current date: =B3-TODAY() Let countdown = "\(diffDateComponents.month) m: \(diffDateComponents.day) d: \(diffDateComponents.hour) h: \(diffDateComponents.Let’s say we need to track the progress of a project daily and see how many days are remaining until the deadline. Let diffDateComponents = NSCalendar.currentCalendar().components(, fromDate: currentDate, toDate: date, options: NSCalendarOptions.init(rawValue: 0)) Let currentFormatter = NSDateFormatter() ĬurrentFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"ĬurrentFormatter.timeZone = NSTimeZone(abbreviation: "GMT+2:00")
Let date: NSDate = futureDateFormatter.dateFromString(releaseDate!)! Let futureDateFormatter = NSDateFormatter()įutureDateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
COUNTDOWN TO DATE HOW TO
You can see it "counting" when the user is scrolling up and down cells on a UITableView as the cells do refresh the view.Īnother thing is that I have on NSTimeZone of the currentDate "GMT+2:00" as it works for my time but only because I haven't figured out how to use the device NSTimeZone yet. The only thing that troubles me is that it doesn't really countdown as the user has to refresh the page for it to recount. Print("day:", daysLeft ? "N/A", "hour:", hoursLeft ? "N/A", "minute:", minutesLeft ? "N/A")ĬountDownLabel.text = "\(daysLeft ? 0) Days, \(hoursLeft ? 0) Hours, \(minutesLeft ? 0) Minutes" Let minutesLeft = CompetitionDayDifference.minute Let hoursLeft = CompetitionDayDifference.hour Let daysLeft = CompetitionDayDifference.day Let CompetitionDayDifference = calendar.dateComponents(, from: currentDate!, to: competitionDay) Let competitionDay = userCalendar.date(from: competitionDate as DateComponents)!
Let currentDate = calendar.date(from: components) Let components = calendar.dateComponents(, from: date as Date)
Hope that helps you guys if you're facing the same struggle as I haveĬleaned up/updated for latest Swift version of the accepted answer. Var minutesLeft = CompetitionDayDifference.minute Var hoursLeft = CompetitionDayDifference.hour Var daysLeft = CompetitionDayDifference.day finally, here we set the variable to our remaining time Let CompetitionDayDifference = ponents(ĭa圜alendarUnit, fromDate: currentDate!, toDate: competitionDay, here we change the seconds to hours,minutes and days Let da圜alendarUnit: NSCalendarUnit = (.CalendarUnitDay |.
Let competitionDay = userCalendar.dateFromComponents(competitionDate)!ĬompetitionDay.timeIntervalSinceDate(currentDate!) Let userCalendar = NSCalendar.currentCalendar() Let currentDate = calendar.dateFromComponents(components) Let components = ponents(.CalendarUnitHour |. Let calendar = NSCalendar.currentCalendar() Here is the solution of how I managed to create a countdown timer to a specific NSDate, for SO allows Q and A Style Answers.
