Calendar showing GLP-1 injection schedule with marked shot dates for tracking

Weekday names are unreliable anchors for your shot history. The safest way to confirm your last shot date is to check the actual calendar date—the number—rather than whether it was a Monday or Thursday. A date like "January 15" is always the same day, but "last Thursday" shifts depending on what today is.

Why weekday names cause confusion

When you say "I took my shot Thursday," you're relying on your memory of the day of the week. But if today is also a weekday, or if several days have passed, it's easy to lose track of which Thursday you mean. Was it this past Thursday, or the one before? Did you miss a week and forget?

Calendar dates—the actual numbers—don't shift. January 15 is always January 15. When you record "January 15" as your shot date, there's no ambiguity about whether that was this week or last week. You can count the days forward from today and know exactly how many days ago your last shot was.

How to read your shot history by date

Open Dose AI and navigate to your dose history. Look for the number associated with each recorded shot. That number is your anchor.

If your last recorded shot shows January 15 and today is January 22, you can count: that's 7 days ago, which is one week. If today is January 29, that's 14 days ago, which is two weeks.

Here's a simple method:

  1. Find the most recent shot date in your history (the number and month).
  2. Count the days forward to today's date.
  3. Divide by 7 to see how many weeks have passed.

If the math feels uncertain, use a calendar app or the calendar on your phone to count the days between the two dates. Most calendar apps show you the number of days between two points.

Recording dates consistently

When you log a shot in Dose AI, always record the actual date—the number—not just the day of the week. If you take your shot on a Thursday, January 16, record "January 16," not "Thursday."

If you're unsure of the exact date, check your phone's calendar, your prescription bottle label, or a recent text or email. Most people's phones automatically timestamp messages and photos, so you can work backward from something you know happened that day.

For ongoing clarity, adopt a consistent shot day. Many people choose a specific date each week—like the 8th and 22nd of each month, or every Wednesday the 10th. A fixed date makes it much easier to check your history later. When you know your shot day is always the 10th, seeing "January 10" in your history immediately tells you it's on schedule.

Using Dose AI's Calendar view

Dose AI displays your shot history in a calendar format, which removes the weekday ambiguity entirely. Each recorded shot appears on its actual date in the calendar grid. You can see at a glance whether your last shot was this week or last week by looking at which row of the calendar it falls into.

The calendar view also shows gaps. If you see your last shot on January 15 and today is January 29, the empty days between them are visible. That empty space tells you immediately that more than a week has passed since your last shot.

Double-checking your history

If you're ever uncertain about a recorded date, Dose AI stores your full dose history with dates and times. Open your history list and verify the most recent entry. The date shown there—the number—is the definitive record of when you last recorded a shot.

If you recorded a shot but aren't sure whether you actually took it that day, or if you're trying to remember whether you logged it, your notes in Dose AI can help. Many people add brief notes like "took shot" or "pen used" to confirm they actually injected on that date. Reviewing those notes alongside the date removes doubt.

Planning ahead with dates

Once you know your last shot date, you can calculate your next shot date. If your last shot was January 15 and you take your shot every 7 days, your next shot is January 22. If your schedule is every 10 or 14 days, add that number to your last shot date.

Dose AI's reminder feature lets you set alerts based on dates, not weekday names. You can schedule a reminder for January 22 at 9 AM, and it will fire on that specific date regardless of what day of the week it falls on. That's far more reliable than "remind me Thursday."

FAQ

What if I recorded the wrong date?

Edit the entry in your dose history. Tap the shot date, correct it to the right calendar date, and save. Your corrected date is now your source of truth.

How do I know if I'm looking at the right month?

Check your phone's date or a calendar app. If you're reviewing old shots from months ago, the month and year are just as important as the day. Dose AI displays the full date to avoid this confusion.

Can I see how many days until my next shot?

Calculate it manually by adding your interval to your last shot date. If your last shot was January 15 and you go weekly, your next shot is January 22. Dose AI's Calendar view makes this visible at a glance.

What if I take my shot on different days each week?

Record the actual date each time. If one week you shoot on Monday January 15 and the next week on Wednesday January 24, both dates are recorded exactly as they happened. Your history shows the real pattern, not an assumed one.

Should I record the date I took the shot or the date I plan to take it?

Record the date you actually took the shot. Your history is a record of what happened, not a schedule. Use reminders for future shots, and log the date only after you've injected.
