Days, sleeps and the age you turn
The countdown runs to midnight at the start of the birthday in your time zone. "Sleeps" is the number of nights left: on the day before the birthday there is 1 sleep. Add the year of birth and the board says the age: someone born in 1996 turns 30 on their birthday in 2026. Save each family member's birthday and My countdowns lists them all with the days left.
Birthdays on 29 February
There is no single rule for which day a 29 February birthday falls on in other years. In Scotland, the Age of Legal Capacity (Scotland) Act 1991 (section 6) takes it to be 1 March; plenty of families celebrate on 28 February instead. The next 29 February dates are 29 February 2028, 29 February 2032, 29 February 2036, 29 February 2040. Pick 29 February in the box and choose whether the countdown should go to 28 February or 1 March in the other years.
Ideas for the countdown
- Full screen it on a TV or tablet the week before a child's party: the days and blocks are big enough to read across a room.
- Send a grandparent the link so they see the same countdown on their phone.
- Keep a list: My countdowns shows every saved birthday with the days left.
Questions and answers
How many sleeps until my birthday?
The board shows sleeps under the units: the number of nights between today and the birthday. It changes at midnight on your device.
Which time zone does it use?
Yours. A date with no time counts to midnight at the start of that day on your device. If you add a time, the countdown remembers the time zone you set it in, so a shared link reaches zero at the same moment for everyone, and each person sees it in their own local time.
Where are my countdowns saved?
Only in this browser, in local storage. Press Save to add one to My countdowns; it is there the next time you open any TimerNook countdown page on this device. Clearing your browser data removes them. Nothing is sent to us.
Can I share a birthday countdown?
Yes. Copy link puts the name, month, day and (if you added it) the year in the link, so the receiver sees the same age. Leave the year out if you would rather not share it.
