# Time Adder

Enter comma-separated durations in HH:MM format to calculate their total.

## Input data

- **Durations (HH:MM)** - type: text; default: 01:30, 00:45, 02:15; Separate values with commas, for example 1:30, 0:45, 2:15

## How it works

Every duration is converted to minutes, all values are added, then the total is formatted as hours and minutes.

## Quick examples

- **Three durations** - Durations (HH:MM): 01:30, 00:45, 02:15
- **Daily work totals** - Durations (HH:MM): 07:30, 07:30, 07:30, 07:30, 07:00
- **Short intervals** - Durations (HH:MM): 00:15, 00:20, 00:25

## Understanding your result

The result can exceed 24 hours because it represents an accumulated duration, not a clock time.
