Visualize Time Intervals

Ever wish you could see your time schedule instead of scanning rows of text? That’s exactly what the Visualize Time Intervals Tool does. Just paste in a list of time ranges like 08:00-09:30, and it’ll build a full-day visual timeline from midnight to midnight.

It splits the day into 15-minute blocks and uses character graphics to show which time slots are busy. Want each 15-minute block to take up more space? You can customize the block width. It’s simple, fast, and makes your schedule immediately more readable.

The Visualize Time Intervals Tool helps turn basic text intervals into a chart-like output no spreadsheets or chart libraries required.

How to Use:

  1. Paste your schedule: Input time ranges in the format HH:MM-HH:MM, one per line.
  2. See the visual instantly: As soon as you enter or import, the timeline appears.
  3. Customize display: Adjust the “Character Block Width” option to make each 15-minute chunk wider (up to 4 characters).
  4. Import from file: Upload .txt, .csv, or similar to populate the input box.
  5. Clear everything using the “Clear All” button whenever you want to reset.

What Visualize Time Intervals Tool can do:

This tool takes a list of daily intervals like 13:00-14:45 or 10:15-11:00 and renders them in a full-day breakdown. Each hour shows four blocks (15 minutes each), with empty slots as dots (·) and filled slots as solid blocks (█).

So if you work from 08:00 to 09:30, that time slot appears filled on the timeline. Multiple time entries layer together to give you a compact, readable schedule.

You can even set how wide each 15-minute block appears, making it easier to spot patterns or gaps in a dense schedule.

This tool is completely visual but stays inside plain text ideal for copy/paste, code, logs, or docs.

Example:

Input:

08:00-09:30
10:15-11:00
13:00-14:45
15:30-16:00

Output:

08:00 │ ████
09:00 │ █···
10:00 │ ·██·
11:00 │ ····
...
15:00 │ ·██·
