Two calendars, one family
In Saudi Arabia and across the Gulf, the dates that matter most don’t live in one calendar. Birthdays and wedding anniversaries are Gregorian. Eid Al-Fitr, Eid Al-Adha and Ramadan are Hijri. A grandmother may count her age in Hijri years; her grandchildren celebrate theirs in Gregorian.
This is completely normal here — and completely unsupported by the tools we use. Default phone calendars treat the Hijri date as decoration, not as something you can plan around.
The eleven-day drift
The Hijri year is about 11 days shorter than the Gregorian year, so every Islamic occasion arrives roughly 11 days earlier each Gregorian year. Eid never lands on the same date twice in a row.
That drift is why the "I’ll remember it, it’s in April" instinct fails. It was in April — last year. This year it’s in March, and by the time the family group chat lights up, the good gifts need ordering time you no longer have.
Reminders that fire too late are not reminders
Even when we do save a date, the default reminder fires the morning of. For a message, that’s fine. For a gift that needs choosing, a card that needs writing, and a delivery that needs scheduling, the-morning-of is a missed occasion with extra guilt.
A useful reminder has to know two things: the real date in the right calendar, and how much lead time a considered gift actually needs.
How Tabtila handles it
Tabtila starts with people, not products. You add your loved ones once — relationship, birthday, anniversary, the Eids they celebrate. Gregorian dates stay Gregorian; Hijri occasions are tracked in the Hijri calendar and converted correctly for every single year, automatically.
Then the reminders do the work: on the first of every month, one digest email lists everything coming up — including the first week of the next month, so nothing sneaks up on you. And about three days before each occasion, you get a nudge with enough time to order something they’ll love.
Both calendars, one place, reminders that respect how gifting actually works. That’s the whole idea.
