This tutorial shows multiple ways to find the number of days between two dates.
DateTime
object is using the Duration difference
method, Duration.inHours
is also used to find the difference between two dates in the number of hours.First Created two dates with the DateTime
constructor and now()
Next, find the difference between two dates using the difference()
method. It returns the Duration
object which returns the number of days using the inDays
property.
Syntax
Duration difference(DateTime other)
Similarly, you can call Duration.inHours
to return the number of hours and divide by 24 to get the days to count.
Here is an example program to find differences in days between two dates.
void main() {
final date1 = DateTime(1990, 03, 03);
final date2 = DateTime.now();
final differenceDays = date2.difference(date1).inDays;
final differenceDays1= (date2.difference(date1).inHours/24).round();
print(differenceDays);
print(differenceDays1);
}
Output:
11724
11724
To get the number of years counted between two dates, you can use inDays
divided by 365.
void main() {
final date1 = DateTime(1990, 03, 03);
final date2 = DateTime.now();
final differenceDays = date2.difference(date1).inDays;
final differenceDays1 = (date2.difference(date1).inHours / 24).round();
final differenceYears = (date2.difference(date1).inDays / 365).floor();
print(differenceDays);
print(differenceDays1);
print(differenceYears);
}
Output:
32
