Web alarm clock for 9:59 a.m.
As you finish registering a birth at the city hall, set the 9:59 am alarm as your cue to collect the certificate, check that you have every document, and leave the counter. The signal arrives just before 10:00 am, giving you a clear endpoint instead of letting one last question delay your departure.
Your city hall visit may end amid conversations, footsteps, and announcements, so choose a volume you can hear from inside a pocket or bag. Test the sound once before relying on it, then keep the phone nearby rather than under papers. A browser alarm cannot mark the end of the birth registration if its page is closed or the phone has gone to sleep, so leave both active until it rings.
Leaving the city hall near late morning often means stepping into busier corridors and streets as queues grow and lunchtime traffic begins to build. Before walking away, move to a quieter spot and check the certificate details against your documents. At 9:59 am, nearby voices may make a brief signal easy to miss, so use vibration as a second cue and avoid burying the phone in a packed bag.
