What you can do here

Useful outcomes you get right away:

• Count backward from a go-live, invoice due date, or vacation anchor
• Keep whole-day precision when HR or legal cares about calendar midnights
• Bookmark or share the URL so finance sees the same backward count you do

Fewer off-by-one surprises near DST

When you leave clock time off, we anchor at noon in the active zone so daylight-saving flips are less likely to nudge your wall clock the wrong way around midnight.
