About MyDayStamp

MyDayStamp started with a simple observation: the internet is full of date calculators, but most of them are cluttered, slow, or feel like they were built decades ago. We wanted something different — calculators that are fast, clear, and pleasant to use on a phone, since that's where most people actually reach for them.

Every tool on this site runs entirely in your browser. We don't ask for an account, we don't store the dates you enter, and we don't sell your data — because there isn't any to sell. You type in a date, we do the math, and that's the whole transaction.

If there's a calculator you wish existed, let us know.
