PST to CST Calculator

Quick Summary

Our pst to cst converter calculator converts time from US Pacific Time (PST / PDT) to US Central Time (CST / CDT) step-by-step.

Central Time (covering Chicago, Houston, Dallas, Minneapolis, and Mexico City) is always exactly 2 hours ahead of Pacific Time (covering Los Angeles, San Francisco, Seattle, and Vancouver). West Coast teams scheduling calls with Central Time clients need to add 2 hours to their local time.

By entering any Pacific clock time, this calculator adds 2 hours to output the exact Central local time in both 12-hour AM/PM and 24-hour clock formats, flagging any late evening day rollovers into the next calendar day.

How It Works: The 2-Hour Pacific-to-Central Time Offset

Converting PST to CST adds 2 hours to Pacific Time:
1. **Offset Addition:** $T_{\text{CST}} = T_{\text{PST}} + 2 \text{ hours}$.
2. **Standard Time Offset:** PST (UTC-8) vs CST (UTC-6) $\rightarrow -8 + 2 = -6 \text{ (CST)}$.
3. **Daylight Saving Time Offset:** PDT (UTC-7) vs CDT (UTC-5) $\rightarrow -7 + 2 = -5 \text{ (CDT)}$.
4. **Day Shift Check:** If $T_{\text{PST}} \ge 10:00 \text{ PM}$ (22:00), Central time falls on the next calendar day.

Formula Explanation

Central Time is calculated from Pacific Time using the following equation:

Step-by-Step Worked Example

Here is a detailed 5-step breakdown for converting 12:00 PM PST (Noon, 12:00) to CST:

1. Step 1 (Identify Pacific Time): Input $= \mathbf{12:00 \text{ PM PST (12:00)}}$.
2. Step 2 (Apply 2-Hour Addition): $12:00 + 2 \text{ hours} = \mathbf{14:00 \text{ (02:00 PM)}}$.
3. Step 3 (Determine AM/PM): $14:00$ corresponds to **02:00 PM**.
4. Step 4 (Format 24-Hour String): 24-hour clock string $= \mathbf{14:00}$.
5. Step 5 (Check Calendar Day Boundary): 02:00 PM is on the **Same Calendar Day**, delivering **CST Time = 02:00 PM**!
