|---|---|---|
| How many workdays are available? | 23 weekday slots | Subtract local holidays, PTO, and shutdown days. |
| What day does the month start/end? | Starts on Wednesday; ends on Friday | Check whether deadlines roll to the next business day. |
| How should billing or payroll be estimated? | 23 Monday-Friday days | Apply your official company, bank, or country calendar. |

| Decision | Recommended handling |
|---|---|
| Need a neutral estimate? | Start with 23 business days and document that holidays are not removed. |
| Need payroll, SLA, or legal precision? | Subtract official holidays, organization shutdowns, and local cutoff rules from the baseline. |
| Need adjacent-month context? | Compare the previous and next month so deadlines do not bunch at the month boundary. |
December often contains company shutdowns and public holidays. Use the 23 weekday baseline first, then subtract Christmas, Boxing Day, New Year transition days, or local observances that apply to your location.
