Medication Schedule Calculator
Stay on track with your medication by generating a clear and simple schedule. Enter the time of your first dose, how often you need to take it, and the total number of doses. This tool will create a detailed timetable for you to follow.

How the Schedule is Generated

Iterative Calculation

The medication schedule is created through a simple loop that adds the specified interval repeatedly to generate the time for each subsequent dose.

  1. Set the Starting Point: The calculator begins with the date and time of your first dose.
  2. Loop and Add: It then enters a loop that runs for the total number of doses you specified.
    • In each cycle, it records the current dose time.
    • Then, it adds the dose interval (e.g., 4 hours) to the current time to find the time for the *next* dose.
  3. Repeat: This process repeats until the schedule is complete for all required doses.

Example From Your Schedule

Based on your inputs, here's how the first few doses were calculated:

  • First Dose: Starts at Dec 1, 2025 at 8:00 AM.
  • Second Dose: The interval of 4 hours and 0 minutes is added to the first dose time, resulting in 12:00 PM.
  • Third Dose: The same interval is added to the second dose time, resulting in 4:00 PM.
  • This continues for all 6 doses.
