LESS COUNTING. MORE CLARITY.
Date & time, simplified.
Plan ahead, find the difference, and make time work for you.
Date difference
Updates automatically as you change dates.
Calendar dates only. Daylight saving changes do not affect the day count. Reversed dates are shown as an absolute difference.
Age calculator
Updates automatically as you change dates.
Time zone converter
Converts automatically as you change the time or zones.
Uses your browser’s time-zone database. For repeated times during the autumn clock change, the earlier occurrence is used and flagged.
Timestamp converter
Type or paste a value to convert automatically.
Accepts epoch seconds or milliseconds (including negative values), ISO 8601, YYYY-MM-DD HH:mm:ss, MM/DD/YYYY or DD/MM/YYYY, and English month dates such as 16 Oct 2026 12:30 GMT. Use Z, UTC, GMT, or an offset such as +05:45. Dates without an offset default to UTC; date-only inputs use midnight. Precision: milliseconds.
