Pick a first time and an interval, and see the full 24-hour clock schedule. Times only, never doses.
| Interval | A pattern some facilities use |
|---|---|
| q4h | 0600 · 1000 · 1400 · 1800 · 2200 · 0200 |
| q6h | 0600 · 1200 · 1800 · 2400 |
| q8h | 0600 · 1400 · 2200 |
| q12h | 0900 · 2100 |
| q24h | 0900 |
These rows are examples, not rules. Standard administration times are set by each facility's policy, and the pharmacy's schedule on the MAR is what governs when a dose is actually given. Where those differ from anything on this page, they win.
Hospitals standardize administration times on purpose. q6h does not mean "whenever, four times." It means a fixed interval, and facilities pin that interval to a published clock pattern so that handoffs, pharmacy dispensing, lab draws, and the eMAR all line up. That is why two units can both run q6h and still use different hours.
BID, TID and QID are not the same as q12h, q8h and q6h. The q-intervals are evenly spaced around the clock, through the night. BID, TID and QID follow a facility-set daytime pattern instead, often tied to meals and to when staff are on the floor, so their gaps are uneven. There is no arithmetic that produces them, which is exactly why this page does not try to compute them.
The first time you type is the only anchor here. Change it and every later time shifts with it. If a dose is given late, the rest of the day does not automatically shift with it on the real schedule, so do not use this page to re-plan a missed time.
2400 and 0000 are the same instant. Facility policies write it both ways. This page shows midnight as 0000 and marks the point where the schedule crosses into the next day.
