Prepositions Used with Days of the Week
One of the most common mistakes English learners make is using the wrong preposition before a day of the week. Fortunately, the rules are straightforward once you learn the most common patterns.
Use On for Specific Days
The preposition on is used before a particular day or part of a day.
| Pattern | Example |
|---|---|
| on + day | I have a dentist appointment on Monday. |
| on + day + morning/afternoon/evening | We are meeting on Friday afternoon. |

Use By for Deadlines
Use by when something must be completed no later than a certain day.

| on weekdays | The library opens early on weekdays. |

Capitalization Rule for Days of the Week

| Wednesday | wednesday |
| Thursday | thursday |
| Friday | friday |
| Saturday | saturday |
| Sunday | sunday |

Pronunciation Tips
Most day names end with -day, pronounced /deɪ/. However, a few names can be challenging for learners.
| Day | Pronunciation Tip |
|---|---|
| Wednesday | Pronounced /ˈwenz.deɪ/. The first “d” is silent. |
| Tuesday | Starts with a clear /t/ sound. |
| Thursday | Begins with the /θ/ sound, like think. |
| Saturday | Often spoken quickly as SAT-er-day. |
