In the ISO 8601 format, durations and intervals are Oman Phone Number represented using the "P" and "T" designators. The "P" designator is used to indicate that a duration is being represented, while the "T" designator is used to separate the date from the time in a duration.
For example, if you wanted to represent a duration of 3 days, 2 hours, and 30 minutes, you would write it as "P3DT2H30M". This tells you that the duration is 3 days, 2 hours, and 30 minutes long.

Similarly, if you wanted to represent an interval, such as the period from January 1, 2020, to December 31, 2020, you would write it as "2020-01-01T00:00:00/2020-12-31T23:59:59". This tells you that the interval is from the beginning of January 1, 2020, to the end of December 31, 2020.
One of the unique aspects of ISO 8601 is that it allows for the representation of complex durations and intervals. For example, you could represent a duration of 1 year, 6 months, 2 days, 3 hours, and 15 minutes as "P1Y6M2DT3H15M". This makes it easy to understand exactly how long a duration or interval is without needing to do any additional calculations.
