The MyTempos date calculator adds or subtracts any number of days, weeks, months, or years from a starting date. Pick your start date, choose whether to add or subtract, enter an amount and unit — the result appears instantly without pressing any button.

The result panel shows the target date alongside a breakdown in multiple units, so you can see the same answer expressed as days, weeks, or months at once. A mini calendar highlights the result in context of the month it falls in.

Every result generates a unique shareable link that encodes your inputs. Anyone who opens the link sees the same calculation instantly — no account needed. The URL updates as you change inputs, so you can always copy the link mid-calculation.

Common uses include calculating contract end dates, finding the date 30, 60, or 90 days from today, working out notice periods, scheduling project milestones, or checking what date falls exactly one year from any given day.
