In this article, learn how to Calculate relative time in C# by using simple inbuilt Math functions. The relative time text such as for now, less than a minute, about a minute, about an hour, about a month, about a year are calculated. Calculate relative time in C#: . /// /// Function to calculate the relative date for the given date time which is older than today's date. (C# 6) /// /// DateTime object which is older than today's date /// The relative date public static string ToRelativeDate(DateTime dtOldDateTime) { TimeSpan oSpan = DateTime.Now.Subtract(dtOldDateTime); double TotalMinutes = oSpan.TotalMinutes; string sSuffix = " ago"; if (TotalMinutes < 0.0) { TotalMinutes = Math.Abs(TotalMinutes); sSuffix = " from now"; } var aValue = new SortedList(); aValue.Add(0.75, () => "less than a minute"); aValue.Add(1.5, () => "about a minute"); aValue.Add(45, () => string.Format("{0} minutes", Math.Round(TotalMinutes))); aValue.Add(90, () => "about an hour"); aValue.Add(1440, () => string.Format("about {0} hours", Math.Round(Math.Abs(oSpan.TotalHours)))); // 60 * 24 aValue.Add(2880, () => "a day"); // 60 * 48 aValue.Add(43200, () => string.Format("{0} days", Math.Floor(Math.Abs(oSpan.TotalDays)))); // 60 * 24 * 30 aValue.Add(86400, () => "about a month"); // 60 * 24 * 60 aValue.Add(525600, () => string.Format("{0} months", Math.Floor(Math.Abs(oSpan.TotalDays / 30)))); // 60 * 24 * 365 aValue.Add(1051200, () => "about a year"); // 60 * 24 * 365 * 2 aValue.Add(double.MaxValue, () => string.Format("{0} years", Math.Floor(Math.Abs(oSpan.TotalDays / 365)))); return aValue.First(n => TotalMinutes < n.Key).Value.Invoke() + sSuffix; } .
